ところで、上述のような表皮の端末は、複数のファスナーによって点で支持された状態となっている。そのため支持面積が局所的であり、支持面積を増やして、表皮の支持剛性を向上させるためには多数のファスナーが必要となる。
しかしながら、多数のファスナーを用いるとなると、その数の分だけ表皮の着脱作業に手間がかかったり、部品調達やベース部材の製造に係るコストの面で不都合が生じたりする場合があった。その結果、表皮の支持剛性を向上させにくいという問題があった。 By the way, the terminal of the skin as described above is in a state of being supported at points by a plurality of fasteners. Therefore, the support area is local, and a large number of fasteners are required to increase the support area and improve the support rigidity of the skin.
However, when a large number of fasteners are used, there are cases in which it takes time and effort to attach and detach the skin, and there are inconveniences in terms of costs related to parts procurement and manufacture of the base member. As a result, there is a problem that it is difficult to improve the support rigidity of the epidermis.

本発明の課題は、表皮の支持剛性を向上させることが可能な車両用シートを提供することを目的とする。 An object of the present invention is to provide a vehicle seat capable of improving the support rigidity of the skin.

また、第一係止部材が長孔部の外側縁に、当該外側縁の長さ方向に亘って係止されるので、支持面積を増やすことができるとともに、表皮にテンションをかけてクッション材を被覆する際に、第一係止部材が長孔部の外側縁に強く引っ掛かることになる。これによって、表皮の支持剛性をより向上させることが可能となる。
さらに、ベース部材は、長孔部の周辺に設けられる補強部を有するので、長孔部を形成したことによるベース部材の周縁部の剛性低下を補完できる。そして、補強部は、隣り合う長孔部同士を連結するように設けられているので、隣り合う長孔部間におけるベース部材の周縁部の剛性を向上させることができる。 According to the third aspect of the present invention, each of the plurality of engaging portions provided along the direction of the peripheral portion of the base member is elongated along the direction of the peripheral portion of the base member. The end portion of the epidermis can be supported by the long engaging portion. As a result, the support area can be increased, so that the support rigidity of the epidermis can be improved.
Further, since the first locking member is locked to the outer edge of the long hole portion over the length direction of the outer edge, the support area can be increased and the cushion material can be applied by applying tension to the skin. When covering, the first locking member is strongly hooked to the outer edge of the long hole portion. Thereby, it becomes possible to further improve the support rigidity of the skin.
Furthermore, since the base member has a reinforcing portion provided around the long hole portion, it is possible to compensate for a decrease in rigidity of the peripheral portion of the base member due to the formation of the long hole portion. And since the reinforcement part is provided so that adjacent long hole parts may be connected, the rigidity of the peripheral part of the base member between adjacent long hole parts can be improved.

請求項４に記載の発明によれば、ベース部材の周縁部の方向に沿って設けられた複数の係合部のそれぞれが、ベース部材の周縁部の方向に沿って長尺であるため、複数の長尺な係合部によって表皮の端末部を支持した状態とすることができる。これによって、支持面積を増やすことができるので、表皮の支持剛性を向上させることが可能となる。
また、第一係止部材が長孔部の外側縁に、当該外側縁の長さ方向に亘って係止されるので、支持面積を増やすことができるとともに、表皮にテンションをかけてクッション材を被覆する際に、第一係止部材が長孔部の外側縁に強く引っ掛かることになる。これによって、表皮の支持剛性をより向上させることが可能となる。
さらに、ベース部材と第一係止部材との間に抜け抑制部が設けられているので、第一係止部材がベース部材の長孔部から抜けることを効果的に抑制できる。 According to the fourth aspect of the present invention, each of the plurality of engaging portions provided along the direction of the peripheral portion of the base member is elongated along the direction of the peripheral portion of the base member. The end portion of the epidermis can be supported by the long engaging portion. As a result, the support area can be increased, so that the support rigidity of the epidermis can be improved.
Further, since the first locking member is locked to the outer edge of the long hole portion over the length direction of the outer edge, the support area can be increased and the cushion material can be applied by applying tension to the skin. When covering, the first locking member is strongly hooked to the outer edge of the long hole portion. Thereby, it becomes possible to further improve the support rigidity of the skin.
Furthermore, since the drop prevention part is provided between the base member and the first locking member, it is possible to effectively suppress the first locking member from coming out of the long hole part of the base member.

請求項５に記載の発明によれば、ベース部材の周縁部の方向に沿って設けられた複数の係合部のそれぞれが、ベース部材の周縁部の方向に沿って長尺であるため、複数の長尺な係合部によって表皮の端末部を支持した状態とすることができる。これによって、支持面積を増やすことができるので、表皮の支持剛性を向上させることが可能となる。
また、第一係止部材が長孔部の外側縁に、当該外側縁の長さ方向に亘って係止されるので、支持面積を増やすことができるとともに、表皮にテンションをかけてクッション材を被覆する際に、第一係止部材が長孔部の外側縁に強く引っ掛かることになる。これによって、表皮の支持剛性をより向上させることが可能となる。
さらに、第二係止部材が、表皮よりも伸張性の高いシート状素材からなるので、ベース部材のコーナー部や高低差の大きい箇所に生じやすい表皮のダブつきを抑制できる。
また、引掛凸部がベース部材の下面から突出して設けられ、第二係止部材が、当該引掛凸部に係止される孔部を有するので、第二係止部材がシート状素材であっても、表皮の端末部をベース部材の周縁部に係合させやすくなる。 According to the fifth aspect of the present invention, each of the plurality of engaging portions provided along the direction of the peripheral portion of the base member is elongated along the direction of the peripheral portion of the base member. The end portion of the epidermis can be supported by the long engaging portion. As a result, the support area can be increased, so that the support rigidity of the epidermis can be improved.
Further, since the first locking member is locked to the outer edge of the long hole portion over the length direction of the outer edge, the support area can be increased and the cushion material can be applied by applying tension to the skin. When covering, the first locking member is strongly hooked to the outer edge of the long hole portion. Thereby, it becomes possible to further improve the support rigidity of the skin.
Furthermore, since the second locking member is made of a sheet-like material having a higher extensibility than the skin, it is possible to suppress the skin from being dubbed easily at a corner portion of the base member or a portion having a large height difference.
Further, since the hooking convex portion is provided so as to protrude from the lower surface of the base member, and the second locking member has a hole portion that is locked to the hooking convex portion, the second locking member is a sheet-like material. Moreover, it becomes easy to engage the terminal part of an outer skin with the peripheral part of a base member.

請求項６に記載の発明によれば、引掛部における延出部の全域がベース部材とクッション材の双方に当接するので、第一係止部材が長孔部の外側縁から抜けることをより効果的に抑制できる。 According to the sixth aspect of the present invention, since the entire area of the extending portion of the hooking portion is in contact with both the base member and the cushion material, it is more effective that the first locking member comes off from the outer edge of the long hole portion.

The follower portion 15 is provided between the plurality of attachment portions 6 and 6, and is configured to be deformable following the shape of the corner portion 1b in order to suppress dubbing of the skin 3 in the corner portion 1b. The follower 15 is formed in a bellows shape in the illustrated example, but is not limited thereto.
Note that. Although the follower 15 has a bellows-like structure, it may have a saddle shape or a gather shape, for example. Furthermore, the follower 15 of the present embodiment employs a bellows-like (gutter-like / gather-like) structure as described above. However, it is possible to make the thickness thinner (thinner) than that of the attachment portion 6. A structure that enhances flexibility may be employed.
The follower 15 is suitable for the corner 1b, but is not limited to the corner 1b, and may be disposed at other locations.

また、ベース部材１の周縁部１ａには、上述のようにコーナー部１ｂだけでなく、高低差の大きい箇所１ｃも存在する（図２参照）。そして、当該高低差の大きい箇所１ｃには傾斜があり、当該傾斜の上端と下端に表皮３のダブつきが生じやすい。そこで、表皮３の端末部３ａに沿って複数取り付けられる第一係止部材５のうち、当該高低差の大きい箇所１ｃまたはコーナー部１ｂに配置される第一係止部材５に替えて、第二係止部材１７を用いる。
より詳細に説明すると、高低差の大きい箇所１ｃにおける表皮３のダブつきを抑制するために、係合部はベース部材１のコーナー部１ｂまたは高低差の大きい箇所１ｃに配置されており、図８に示すように、引掛凸部１６と、第二係止部材１７と、を備える。 Further, not only the corner portion 1b as described above but also a portion 1c having a large height difference exists on the peripheral edge portion 1a of the base member 1 (see FIG. 2). And the location 1c with the said large height difference has an inclination, and the upper end and the lower end of the inclination are likely to be dubbed. Therefore, instead of the first locking member 5 that is mounted along the terminal portion 3a of the skin 3 in place of the first locking member 5 that is disposed at the location 1c or the corner portion 1b having a large difference in height, the second locking member 5 is provided. A locking member 17 is used.
More specifically, the engagement portion is disposed at the corner portion 1b of the base member 1 or the portion 1c having a large height difference in order to suppress the drape of the skin 3 at the portion 1c having a large height difference. As shown in FIG. 2, the hooking convex portion 16 and the second locking member 17 are provided.

引掛凸部１６は、ベース部材１の周縁部１ａの方向に沿って、かつ複数の長孔部４と同列に設けられ、ベース部材１の下面から突出するように形成されている。また、当該引掛凸部１６の突出方向は、当該引掛凸部１６に引っ掛けられる第二係止部材１７が容易に外れないように、ベース部材１の中央側に傾くように突出形成されている。
なお、当該引掛凸部１６のある箇所には、第二係止部材１７を引っ掛けて装着させるための隙間を形成する装着用孔１６ａが形成されている。 The hooking convex portion 16 is provided along the direction of the peripheral edge portion 1 a of the base member 1 and in the same row as the plurality of long hole portions 4, and is formed so as to protrude from the lower surface of the base member 1. The protruding direction of the hooking protrusion 16 is formed so as to be inclined toward the center of the base member 1 so that the second locking member 17 hooked on the hooking protrusion 16 does not easily come off.
Note that a mounting hole 16 a that forms a gap for hooking and mounting the second locking member 17 is formed at a location where the hooking projection 16 is present.

第二係止部材１７は、表皮３の端末部３ａに沿って取り付けられ、引掛凸部１６に係止される孔部１７ａを有する。また、当該第二係止部材１７は、表皮３よりも伸張性の高いシート状素材からなる。当該シート状素材としては例えばターポリン等のような柔軟性に優れる樹脂製シートが採用されている。
なお、本実施の形態の引掛凸部１６の幅寸法は、長孔部４と略等しく設定されており、第二係止部材１７の孔部１７ａも、当該引掛凸部１６の幅寸法に対応した形状とされている。 The second locking member 17 is attached along the terminal portion 3 a of the skin 3 and has a hole portion 17 a that is locked to the hooking convex portion 16. In addition, the second locking member 17 is made of a sheet-like material that is more extensible than the skin 3. As the sheet material, for example, a resin sheet having excellent flexibility such as tarpaulin is adopted.
In addition, the width dimension of the hook convex part 16 of this Embodiment is set substantially equal to the long hole part 4, and the hole part 17a of the 2nd latching member 17 also respond | corresponds to the width dimension of the said hook convex part 16. The shape is made.

以上のような構成の車両用シートにおいて、表皮３によってクッション材２を被覆し、かつその端末部３ａをベース部材１の周縁部１ａに支持させる際は、概略的には、第一係止部材５の引掛部７を長孔部４の外側縁に係止するだけでよい。また、コーナー部１ｂおよび高低差の大きい箇所１ｃにおいても、追従部１５を有する第一係止部材５を用いたり、第二係止部材１７を用いたりすれば、表皮３のダブつきを抑制しつつ、当該表皮３によってクッション材２を被覆することができる。 In the vehicle seat having the above-described configuration, when the cushion material 2 is covered with the skin 3 and the terminal portion 3a is supported by the peripheral edge portion 1a of the base member 1, the first locking member is schematically shown. It is only necessary to lock the five hook portions 7 to the outer edge of the long hole portion 4. Further, even in the corner portion 1b and the portion 1c having a large height difference, the use of the first locking member 5 having the follow-up portion 15 or the second locking member 17 suppresses the drape of the skin 3. However, the cushion material 2 can be covered with the skin 3.

本実施の形態によれば、ベース部材１の周縁部１ａの方向に沿って設けられた複数の係合部のそれぞれが、ベース部材１の周縁部１ａの方向に沿って長尺であるため、複数の長尺な係合部によって表皮３の端末部３ａを支持した状態とすることができる。
これによって、例えば表皮３を点で支持するようなファスナー等を用いる場合に比して、支持面積を増やすことができるので、表皮３の支持剛性を向上させることが可能となる。
また、係合部の一つ一つが長尺であるため、ベース部材１の周縁部１ａに設けられる係合部の数も少なくすることができるので、表皮３の着脱も容易となる。また、このように表皮３の着脱が容易となれば、表皮３の交換性を向上させることができる。 According to the present embodiment, each of the plurality of engaging portions provided along the direction of the peripheral edge portion 1a of the base member 1 is elongated along the direction of the peripheral edge portion 1a of the base member 1. The terminal portion 3a of the skin 3 can be supported by a plurality of long engaging portions.
Accordingly, for example, the support area can be increased as compared with the case where a fastener or the like that supports the skin 3 with dots is used, so that the support rigidity of the skin 3 can be improved.
In addition, since each of the engaging portions is long, the number of engaging portions provided on the peripheral edge portion 1a of the base member 1 can be reduced, so that the outer skin 3 can be easily attached and detached. Moreover, if the attachment and detachment of the skin 3 becomes easy in this way, the exchangeability of the skin 3 can be improved.

また、第一係止部材５が長孔部４の外側縁に、当該外側縁の長さ方向に亘って係止されるので、支持面積を増やすことができるとともに、表皮３にテンションをかけてクッション材２を被覆する際に、第一係止部材５が長孔部４の外側縁に強く引っ掛かることになる。これによって、表皮３の支持剛性をより向上させることが可能となる。さらに、単に第一係止部材５を長孔部４の外側縁に引っ掛けるだけで表皮３をベース部材１の周縁部１ａにおいて支持できるので、表皮３の着脱が容易となる。
したがって、表皮３の支持剛性をより向上させたいという要望に対して好適に対応できる。 In addition, since the first locking member 5 is locked to the outer edge of the long hole portion 4 over the length direction of the outer edge, the support area can be increased and tension is applied to the skin 3. When covering the cushion material 2, the first locking member 5 is strongly hooked to the outer edge of the long hole portion 4. As a result, the support rigidity of the skin 3 can be further improved. Furthermore, the skin 3 can be supported on the peripheral edge 1a of the base member 1 simply by hooking the first locking member 5 to the outer edge of the long hole portion 4, so that the skin 3 can be easily attached and detached.
Therefore, it is possible to suitably respond to the desire to further improve the support rigidity of the skin 3.

また、引掛部７のうち少なくとも一部は、ベース部材１とクッション材２の双方に当接するので、第一係止部材５が長孔部４の外側縁から抜けることを抑制できる。
しかも、引掛部７における延出部９の全域がベース部材１とクッション材２の双方に当接するので、第一係止部材５が長孔部４の外側縁から抜けることをより効果的に抑制できる。
