Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a seat for a passenger car.

<Prior Art> The entire front seat of a passenger car can be moved and adjusted in the longitudinal direction by a seat adjuster, and the backrest can be tilted forward by a seat recliner.

<Problem that the invention aims to solve> When getting in and out of the rear seat of a two-door car,
The backrest of the front seat is tilted forward and the entire seat is moved to the very front to secure as much space as possible for getting on and off. causing inconvenience to

<Means for Solving the Problems> In order to solve the above-mentioned conventional problems, the present invention provides a front seat of a passenger car that allows the backrest to pivot forward using the side end of the backrest on the side of the center of the passenger compartment as a fulcrum. The backrest is pivotably mounted on the seat by being biased toward the end of the pivot movement by a spring, and a locking device is provided at the side end of the backrest on the door side, which can be engaged with and detached from the seat.

<Operation> In the present invention, by releasing the lock of the backrest in its normal position by the locking device, the backrest rotates forward using the side end on the center side of the passenger compartment as a fulcrum by the turning biasing force of the coil spring.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. In Fig. 1, 1 is the seat, 2 is the backrest,
3 is the frame pipe of the backrest. The present invention provides a backrest 2 in the frame pipe 3.
The frame pipe 3a at the side end on the center side of the passenger compartment is pivotably supported on the lower pipe 4a fixed to the frame of the seat part 1, and the frame pipe 3b at the side end on the door side of the backrest 2 is attached to the seat part. A locking device is provided on the lower pipe 4b fixed to the frame 1.

The configuration of the present invention described above will be explained in more detail.
As shown in FIG. 2, the pivot structure between the frame pipe 3a and the lower pipe 4a is such that a bush 5 is fixed in the lower pipe 4a and a bush 6 is fixed in the frame pipe 3a.
Insert the shaft 7 into the hole 6. Furthermore, both buttons 5 and 6
It has a structure in which the winding ends of the coil spring 8 are fixed in between.

On the other hand, the structure of the locking device is as shown in FIGS.
A lock shaft 10, which is fitted into and removed from the lower pipe 4b, is inserted into the bush 9 so as to be slidable in the axial direction, and a coil is provided between the bush 9 and the lock shaft 10 to constantly press and move the lock shaft 10 downward. A spring 12 is provided. Furthermore, frame pipe 3b
, an elongated hole 13 in the axial direction and a locking hole 14 in the circumferential direction perpendicular to the axis are provided at the upper end of the elongated hole 13, and the knob 11 guided in the elongated hole 13 and the locking hole 14 is provided. It has a structure fixed to the lock shaft 10.

Since the present invention has the above-described structure, when the backrest 2 is in its normal state, the lock shaft 10 is fitted into the lower pipe 4b by the repulsive force of the coil spring 12, and the rotation of the backrest 2 is restrained.

When the backrest 2 is pivoted forward from the normal state, when the knob 11 is lifted, the lock shaft 10 rises against the repulsive force of the coil spring 12 and is pulled out from the lower pipe 4b. In this state, the unlocked state is maintained by locking the knob 11 into the locking hole 14.

When the lock is released, the backrest 2 rotates forward using the shaft between the frame pipe 3a and the lower pipe 4a as a fulcrum by the repulsive force of the coil spring 8, and spins toward the center of the vehicle compartment, thereby securing a large space on the door side. It is something.

<Effects of the invention> As described above, according to the invention, the backrest can be pivoted forward using the side edge on the center side of the passenger compartment as a fulcrum. The side edge on the door side does not get in the way,
Easy to get on and off. In addition, the forward rotation of the backrest is automatically achieved by the repulsive force of the coil spring at the pivot point provided at the side end on the center side of the passenger compartment by unlocking the locking device provided at the side end on the door side. It has the advantage of being
