Description

[Detailed description of the invention] This invention is a fixing device for vehicle (automobile) seats.
More specifically, the present invention relates to an improvement in a fixture consisting of a support piece and a hook piece, which is provided between the upper side of the seat bag and the wall surface of the vehicle body which the upper portion faces, and which connects the seat bag to the wall surface of the vehicle body.

Figure 1 A and B show conventional products, in which a' is a support piece b that is fixed to the car body wall a, and a hook that is fixed to the left and right sides of the seat back cover and hooked to the hook part _a'1 of the annular support piece. The hooking portion a′ ₁ of the support piece a′ is horizontally protruded with respect to the vehicle body wall surface A, and this hooking portion a′ ₁
The structure was such that the left and right upper portions of the seat back cover were fixed to the vehicle body wall A by hooking hooks B to the seat backrests. Therefore, if a load is applied to the seat back cover in the front-back direction, there is a risk that the seat back cover will bend and the hook b in the latched state will slip through in the lateral direction, causing the seat back cover to fall backwards (Fig. 1 A).This problem has been eliminated. In order to do this, the seat back had to be reinforced so that it would not bend under the load, which impeded weight reduction.

In the figure, _a'2 is a fixing part that fixes the hook part _a'1 to the side surface A of the vehicle body.

Therefore, the present invention was developed in view of the above circumstances, and its basic structure is to provide a retaining wall portion formed vertically at the end of the latching portion of the support piece to prevent the seat back from bending and deforming. It is designed to ensure that the hook stays in place even when the hook is in place.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, A indicates a fixing device according to the present invention, and the illustrated fixing device A has its supporting piece a fixed to the vehicle body wall surface A, and its hook pieces b fixed to the upper left and right sides of the seat back cover. The upper part of the seat back cover is supported and fixed to the vehicle body by hooking the hook piece b to the support piece a, and when the hook piece b is removed, the seat back cover is folded forward and stacked on the seat cushion (c). It has a structure that allows luggage etc. to be loaded on it.

The support piece a has a fixing part _a3 fixed to the vehicle body wall surface A with screws, a hooking part _a2 fixed to the fixing part _a3 , and a retaining wall part a provided at the tip of the hooking part _a2 . The hanging part _A2 and the retaining wall part _A3 are formed by bending a single wire rod, and _{the retaining part A2 is} horizontal to the car body wall surface A, and the retaining wall part A ₃ is the hook part a ₂
They are each formed perpendicular to the (Fig. 3) On the other hand, the hook piece b that is hooked to this support piece a is made of metal or a hard synthetic resin plate, and is rotatably attached to the upper left and right sides of the seat back cover with pins b ₄ , etc. . (Fig. 2) This hook piece b is the hook part a ₁ of the support piece a.
A hook part b ₁ that engages with the hook part b 1 , an operating part _{b 2 formed} integrally with the hook part b 1 , and a mounting part b ₃ integrally formed with the operating part b ₂ and rotatably pivoted by a pin b ₄ The hook part b ₁ and the operating part b ₂ protrude in opposite directions, and the distance between the hook part b ₁ and the attachment part b ₃ is larger than the wire diameter of the wire forming the hook part a ₁ . A locking groove 1 having a slightly larger groove width is cut out.

In this way, when the operating part _b2 of the hook piece b is pinched and the hook part _b1 is inserted into the catch part _a1 of the support piece a, the wire constituting the catch part _a1 fits into the catch groove 1. The seat backrest is then locked, and the upper part of the seat backrest is fixed to the vehicle body wall. In this fixed state, a part of the retaining wall part _a2 of the support piece a is located inside the operating part _b2 of the hook piece.

Therefore, a force in the direction of the arrow in FIG. 3 acts on the hook b in response to the load in the longitudinal direction of the seat back cover, and the hook b moves in that direction. However, since the retaining wall portion _a2 is provided, the movement of the hook piece b is regulated by the retaining wall portion _a2, and the hook piece b will not be pulled out from the support piece a. In the figure, _b5 is a through hole for inserting pin _b4 . Furthermore, by pinching the operating portion _b2 of the hook b and rotating it upward, the fixed state of the seat back cover is released, the seat back cover falls forward, and the back side thereof can become a loading area for luggage, etc.

As described above, in the present invention, since the retaining wall portion is provided in the moving direction of the hook piece, the movement of the hook piece is regulated by the retaining wall portion, and the support piece can be prevented from coming off from the hooking portion. Therefore, there is no need to reinforce the seat bag to prevent the hook from coming off as in the conventional case, and the weight of the seat bag can be reduced. Alternatively, the tip of the hooking portion of the conventional product may be bent vertically to form a retaining wall portion. Therefore, the structure is simpler and lighter than conventional products. Thus, the initial objective can be achieved.
