Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a removable and foldable sectional seat for a vehicle.

<Prior art and its problems> Conventionally, as shown in Japanese Patent Laid-Open No. 56-31837, for example, as a simple removable seat for a vehicle such as an automobile, a seat between upper and lower rod-shaped members removably installed horizontally on the vehicle body has been used. A flexible sheet material is used. However, in such conventional simple seats, it is necessary to provide a tensioning device to pull the boundary between the seat cushion and the seat back toward the rear body side and maintain the seat shape, which has the disadvantage of requiring a great deal of effort for setting. There is. Furthermore, since the sheet material is partially pulled by the tensioning device, a pulled shape appears, resulting in poor appearance of the seat and poor seating comfort.

<<Object of the Invention>> An object of the present invention is to provide a sectional seat for a vehicle that does not require the use of a tension device, can be easily attached/detached and folded, and has a good appearance.

<<Structure of the Invention>> In order to achieve the above-mentioned object, the sectional seat for a vehicle of the present invention is provided with a suspension pin that removably engages with a bracket fixed to a vehicle body, and has a substantially U-shape. The shaped cushion frame and the back frame are made to intersect with each other in the vicinity of both ends and are hinged to each other so as to be rotatable.
A horizontal member is attached to the other end of the flexible seat cushion material whose one end is fixed to the front edge of the cushion frame, and the other end of the flexible seat cushion material whose one end is fixed to the upper edge of the back frame. A horizontal member is attached, and both ends of the horizontal member of the seat cushion material are removably engaged with an engaging portion provided on the distal side of the hinge portion of the back frame, and the horizontal member of the seat back member is removably engaged. Both ends of the cushion frame are removably engaged with an engaging portion provided on the distal side of the hinge portion of the cushion frame, and tension is applied to each of the seat cushion material and the seat back material by these engagements. It is characterized by:

<<Embodiment of the Invention>> FIG. 1 is a perspective view of one embodiment of an assembled seat for a vehicle according to the present invention.

As seen in the figure, the frame of the sectional seat for a vehicle of the present invention is a combination of a cushion frame 1 and a back frame 2, each made of metal pipes and other materials formed into a substantially U-shape. . At both ends of the cushion frame 1 and the back frame 2, plate-shaped connecting pieces 1a and 2a are integrally fixed by means such as welding. By fixing the part with a hinge pin 3, it is hinged so as to be rotatable. Said cushion frame 1
A seat cushion material 4 and a seat back material 5 are attached to the back frame 2.

Seat cushion material 4 and seat back material 5
The spring material is formed into a flexible plate by covering a spring material such as a thin steel plate with a pad, trim material, etc. The seat cushion material 4 has one end locked to the front edge 1b of the cushion frame 1,
A horizontal member 4a made of a metal pipe or the like is attached to the other end. In addition, seat back material 5
has one end locked to the upper edge 2b of the back frame 2, and a horizontal member 5a similar to the above is attached to the other end. (The figure shows a state in which the seat back material 5 is partially cut out.) The seat cushion material 4 and the seat back material 5 have a cushion frame 1, a back frame 2, and horizontal members 4a, 5a at the ends thereof. The end portion may be attached to these members by known means such as wrapping the end portion around these members and sewing the overlapping portion.

An engaging portion 1c cut out in a semicircular shape is provided on the distal end side of the hinge pin 3 portion of the connecting piece 1a of the cushion frame 1, and an engaging portion 1c cut out in a semicircular shape is provided on the distal side of the hinge pin 3 portion of the connecting piece 2a of the back frame 2. Also provided is an engaging portion 2c cut out in a semicircular shape. When the back frame 2 is erected to set the seat in use as shown in FIG.
c, also the horizontal member 4 of the sheet cushion material 4.
By engaging both ends of a with the engaging portions 2c, the seat cushion material 4 and the seat back material 5 are made to maintain appropriate tension. These tension values can be set appropriately by adjusting the lengths of the seat cushion material 4 and the seat back material 5 in advance.

An appropriate number of suspension pins 6 are installed on each side of the cushion frame 1 and the back frame 2. The seat is installed in the vehicle interior by removably engaging the suspension pin 6 with a bracket 7 fixed at a corresponding location on the vehicle body (not shown) shown in FIG.

FIG. 3 is a side view of the sectional seat for a vehicle of the present invention shown in FIG. 1 (the suspension pin 6 is omitted in this figure), and FIG. Seat cushion material 4 and seat back material 5
It shows the state where tension is applied to. As described above, the seat of the present invention can be installed and removed in the vehicle interior as desired, but when it is removed, the back frame 2 can be moved around the hinge pin 3 from the state shown in Figure 3A. Rotate the cushion frame 1 in the direction of the arrow shown (at this time, the horizontal member 4a
and 5a are removed from the engaging portions 2c and 1c), and can be folded into the state shown in FIG.

In the above illustrated example, the engaging parts 2c and 1c of the horizontal members 4a and 5a are shown as semicircular cutouts of the connecting sides 2a and 1a, but they may also be hook-shaped. do not have. Also, although separate connection pieces 1a and 2a are shown fixed to the cushion frame 1 and the back frame 2, the tips of the cushion frame 1 and the back frame 2 are processed (for example, flattened). Needless to say, they may be connected by hinges.

<<Effects of the Invention>> As is clear from the above explanation, the sectional seat for a vehicle of the present invention does not require a tension device and can be easily set into a vehicle interior without requiring any effort.
Additionally, it can be folded into a compact state when not in use. Furthermore, when in use, appropriate tension is always applied to each of the seat cushion material and the seat back material, so that a good appearance is maintained without generating a drawn shape, and it is possible to use the seat cushion with excellent sitting comfort.
