Abstract

PURPOSE:To prevent a flat tonneau board from being damaged, by forming a disengageable stopper member in a concave part formed in front of a side finisher at the sidepiece of a rear seat back. CONSTITUTION:A plastic side finisher 2 is installed in an inner part of a car body 1, then a concave part is formed in the front of it, and a stopper member 8 at the sidepiece of a seat back 7 of a rear seat 3 is made free of disengagement. The stopper member 8 consists of a plate 13 to be tightly attached to an upper end of a frame 10 of the seat back 7 and a release lever 16 capable of rotation in a through hole 14 in front and in the rear of this plate 13 and its own through hole 23 via a pin 15.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a stopper mechanism for an automatic heavy duty rear seat back.

b. Prior Art A tonneau board is arranged behind a conventional automatic heavy-duty rear seat back, and as shown in Utility Model Application Publication No. 2671/2007, this tonneau board is placed in front of a fixed member of the seat back. A sub-member that can move back and forth by tilting is arranged,
Due to the backward tilt of the seat back, L no vW -k'6"h
However, the structure of the tonneau board is complicated, as the sub-members move back and forth, and there are heavy parts, so the weight increases, so improvements in these areas are desired. OBJECTS OF THE INVENTION In view of the conventional example, the present invention aims to keep the tonneau board as a flat plate and prevent the rear seat back from being easily tilted backwards in order to prevent damage to the tonneau board.

d1 Structure of the Invention In order to achieve the above object, the present invention forms a recess in the front part of a side finisher fixedly installed inside an electric body, and a rear seat back that can be tilted backwards can be freely engaged with and detached from the recess in the side part of the rear seat back. This system is equipped with a stopper member that allows the rear seatback to tilt backwards in the area where the tonneau board is located by operating the stopper member after the seatback is tilted backwards through the so-called reclining operation. This is what I did.

e. Example 1 to 1 show one embodiment of the present invention.

First, to explain the structure, / is the vehicle body, C is the side finisher made of synthetic resin fixed inside the vehicle body, 3
is the rear seat, g is the luggage compartment, and evening is the luggage floor. There is a recess 6 in the front of the side finitus.
A stopper member ♂ provided on the side of the seat back 7 of the rear seat 3 is capable of engaging and disengaging from the recess 6 .

The stopper member t of the rear seat 3 can be tilted backward from the center of rotation 7a by a reclining device (not shown) with respect to the seat cushion.
As shown in Figs. It consists of through-hole arrays on the front and rear sides and a release lever 76 that can be rotated left and right through the bottle B111 in the through-hole J of itself. Reference numeral 17 denotes a coiled spring, which is elastically interposed between the recess t of the grate 13 and the recess 19 of the release lever/6.
6.0S is always biased to engage in the recessed portion.
0 is a part of the suspension ring 17 formed in the release ring 17. Also, on the back side of the concave part of the side finish shaft, as shown in Fig. A stopper member that is provided with a fixed bracket, 2/, that extends over and is added to the recess 6? The load of this rear seat back 7 is supported through the support.

U in FIG. 1 is a guide groove formed in this side finish shaft, which is concentric with the center of rotation 7a of the jet lock 70.

Next, the operation will be explained. Normally, the release lever 6 is located in the recess 6 by the spring 7.

Next, when the reclining device (not shown) is operated and the first release lever 16 is moved from the solid line position in FIG. is moved in the guide groove 34 as shown in FIG. 1. FIGS. 6 and 7 show other embodiments of the stopper member. (according to 7)
The upper end portion 33 of the seat back 7 is formed by recessing the upper layer portion 3/ in a substantially horizontal manner and using three box-shaped housings with a hollow bottom.
A lock pin 3μ, which is flush with the seat back 7 and is movable laterally within the housing 3, controls whether or not the seat back 7 can be tilted backwards with respect to each concave portion of the side finish. Housing J, 2)'! , a wall surface 3g having a through hole that supports the lock pin 31, a support grate 36 that has a support plate, a through hole 77 through which the lock pin 3q can be inserted and retracted, and a sliding elongated hole θ that protrudes from the operating portion 3 of the lock pin 3t. and the lock pin 3t is stretched between the lock pin 3μ and the rod tough of the three housings, and the lock pin 3t is inserted into the through hole 37.
Coiled spring L2 biased in the direction of protruding more
It becomes more.

The support grate 36 may include a first member 3 having a lip shape partially attached to the 3 housings, and a first member having a grate shape adhesively supported on the edge surface of the first member (tj). good.

With this configuration, the operating portion 3wa of the lock pin 3μ can be disengaged from the seat back 2 against the slider cylinder 412, and the seat back 7 can be tilted rearward.

f. Effects As explained above, according to this invention, it is possible to tilt the rear seat back backwards.Furthermore, by creating a stopper member kA, it becomes possible to tilt the rear seat back backwards. Therefore, the tonneau board will not be destroyed by the rear seat back. Therefore, since the rear seat back does not tilt and fall backwards, there are no practical effects such as there is no need for a complicated tonneau board structure as in the past.
