Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back and back board for an automobile seat which is excellent in mounting workability and does not cause a gap between the seat and the seat. Related to the mounting mechanism. 2. Description of the Related Art Conventionally, as a mounting mechanism of a back and back board, for example, Japanese Utility Model Laid-Open Publication No.
As disclosed in JP-A-112148, a plurality of connectors are interposed between a back frame provided with an upper panel for mounting a back board and a lower frame, and a back frame provided between the upper frame and the lower frame. One that is engaged with and held by a panel and a lower frame is known. [0003] However, the conventional mounting mechanism of this type has a problem in that the middle sides of the back-and-back board are not sufficiently fixed to the back frame, so that play occurs during traveling.
In particular, if you have a storage pocket on the back of the seat,
Because both sides of the back board were not fixed, when the pocket was opened, the back board was pulled together with the front, causing a gap between the seat and the seat, causing a problem of poor appearance . On the other hand, various attempts have been made to fix both sides of the back and back board to the back frame with screws or the like in order to improve the fixing force and prevent the occurrence of skidding, but the appearance is impaired and the mounting work is complicated. At present, it has not been put into practical use. [0004] The present invention solves the above-mentioned conventional problems, and maintains a sufficient fixing force by fixing the back and back board to the back frame up, down, left, and right. There is no play during running, and even if the storage pocket provided on the back is opened, there is no gap between the seat and the appearance, and the appearance is excellent. The present invention has been completed for the purpose of providing a back-and-back board mounting mechanism that can be securely fixed. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a back-board mounting mechanism according to the present invention comprises a back frame provided with an upper panel for mounting a back-board and a lower frame. A back-and-back board mounting mechanism in which a back and back boat is attached to and held by the plurality of connecting tools disposed on the back side of the back and back frame to engage and hold the upper panel and the lower frame. The left and right side frames are provided with an inwardly projecting piece serving as a tapered edge protruding in the middle. On the back surface of the back and back boat, an upward hook engageable with the upper panel and a lower engaging member engageable with the lower frame are provided. Left and right resilient side hooks that are always outwardly repelled and engaged with the inner edge of the side frame are provided, and the upper, lower, left and right sides of the back boat are referred to as the upward hooks. Engagement with the upper panel, connection of the lower locking device to the lower frame, and lowering of the back hook boat to engage the upward hook with the upper panel. It is attached to the back frame by means of a resilient side hook which passes through and immediately engages with the side frame. Next, a preferred embodiment of the present invention will be described in detail with reference to a case where the present invention is applied to an illustrated automobile front seat. 1 is a back board, 11 is a back frame. The back frame 11 has an upper panel 12 and a lower frame 13 for mounting the back and back board on the back, and left and right side frames 14, 14 on both sides. Is provided with an inward projecting piece 16 whose inner edge extends downward to form a tapered edge 15. On the other hand, the back board 1 is provided with two upward hooks 2 and 2 which can be engaged with the upper panel 12 and two lower locking tools 3 and 3 which can be engaged with the lower frame 13 on the back surface. Not only that, the left and right sides of the back frame 1 are always bounced outward at the intermediate position on both sides of the back of the back board 1 and are engaged with the inner edges of the side frames 14 immediately above the inward projecting pieces 16. One or more pairs of resilient side hooks 4 are provided. The upper and lower sides of the back and back boat 1 are engaged by the upward hooks 2 with the upper panel 12 and the lower engaging members 3 are engaged with the lower frame 13.
When the back boat 1 is slid upward to engage the upward hook 2 with the upper panel 12, it passes between the inwardly projecting pieces 16, 16 while being compressed and guided by the downwardly expanding tapered edges 15, 15 and immediately above. Side frame 1
It is attached to the back frame 11 without gaps by the resilient side hooks 4 and 4 which are resiliently engaged with 4 and 14. In the figure, reference numeral 5 denotes an elastic locking portion which is bent at the tip of the resilient side hook 4. Next, the back back board 1 is attached to the back frame 11.
The procedure for attaching to the device will be described. First, as shown in FIG. 4, the hooks 2, 2 are hooked on the upper panel 12 while the back back board 1 is attached to the back of the back frame 11, and the elastic side hooks 4 are attached to the back frame 11.
When the entire back board 1 is slid upward from a position located below the inward projecting piece 16 protruding from the side frame 14, the elasticity of the resilient side hooks 4, as shown in FIG. The locking portion 5 passes between the inwardly projecting pieces 16, 16 while being compression-guided by the downwardly expanding tapered edges 15, 15 formed on the inner edges of the inwardly projecting pieces 16, 16, and is immediately above the side frames 14, 14. Since the lower engagement members 3 are engaged with the brackets 13a of the lower frame 13 as shown in FIG. At least two places, it is accurately held on the back of the back frame 11, maintains a sufficient fixing force and does not rattle during running. In addition, even if the storage pocket provided on the back is opened, there is a gap between the seat and the seat. Without causing Flourished also becomes excellent. As described above, in the present invention, despite the fact that the back back board 1 is also locked at the left and right side portions, the back back board 1 is merely slid upward without performing complicated installation work as in the related art. It is possible to secure an excellent design surface without having to fasten a special screw or the like from the outside. As is apparent from the above description, according to the present invention, the back and back board is fixed not only on the upper and lower sides but also on both side portions, so that the back board is maintained with a sufficient fixing force and the backlash during running is maintained. And the appearance is excellent without any gaps between the seats even when the storage pocket provided on the back is opened. Is what you can do. Therefore, the present invention greatly contributes to industrial development as a back-and-back board mounting mechanism that has eliminated the conventional problems.
