Description

[Detailed description of the invention] (Field of industrial application) The present invention is a locking system that uses a combination of a cam and a striker, which is used to hold the rear seat back of an automobile in an upright position. This invention relates to a locking device for an automobile seat, which has a structure such that the seat back can be fully reclined.

(Prior art) In a conventional locking system that combines a cam and a striker, the cam is rotatably attached to the rear end of the rear seat, and the striker is welded to a position on the rear quarter inner panel that corresponds to the upright position of the rear seat. , is fixed. For this reason,
The rear seat can only be set in two positions: upright and forward. Even if a multi-stage adjustment tooth groove were provided on the cam side, the inclination angle of the rear seat could be changed slightly, but it would not be possible to make the rear seat incline significantly or fully recline. In addition, in order to be able to tilt a large amount or fully recline, the welding position of the striker must be aligned with the position of the maximum tilt angle, and a huge cam must be installed, and this locking system However, the drawback was that it lacked practicality.

(Purpose of the invention) The present invention is intended to eliminate the above-mentioned drawbacks, and is an automotive vehicle that allows the seat to be fully reclined by moving the striker to a position that does not hinder the movement of the seat. This provides a seat locking device.

(Structure of the invention) The feature of the invention is that a cam is rotatably attached to the rear end of the rear seat back, and a corresponding part of the vehicle body engages with the cam to maintain the inclination of the seat back. In a locking device for a car seat provided with a striker, a columnar base having a hole that supports the striker in a movable manner so that it can be stored is oriented so that the striker moves forward and backward with respect to the cam of the seat back. It is attached to the inner panel of the vehicle body.

(Function) With the above configuration, the present invention stores the striker in the base when reclining the seat,
The striker can be prevented from interfering with seat movement, and the seat can be fully reclined.

(Example) DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the striker 1
is slidably fitted into a striker fitting hole 3 provided in a prismatic base 2 made of synthetic resin, and a coil spring 4 is installed around the opposite end of the bent gripping portion 1a of the striker 1. A spring force that causes the gripping portion 1a of the striker 1 to protrude from the base 2 side toward the vehicle interior can be applied.

The base 2 is provided with a finger groove 5 that forms a concave portion in the middle of the two striker fitting holes 3 to make it easier to grip the grip part 1a of the striker 1. A gripping part fitting hole 6 perpendicular to the striker fitting hole 3 is formed in the facing end surface 5a. A notch 7 with a width narrower than the hole diameter is provided between the striker fitting hole 3 and the gripping part fitting hole 6, and the gripping part 1
a can be inserted into the gripping part fitting hole 6 from the outside of the base, and the gripping part fitting hole 6
A striker protrusion prevention protrusion 8 is formed to prevent the gripping part 1a contained in the gripping part 1a from popping out from the gripping part fitting hole 6 due to the biasing force of the spring 4.
As a result, the striker 1 can be pushed into the grip fitting hole 6 of the base 2 by pushing the grip part 1a, and the striker 1 can be pulled out from the base 2 by pulling the grip part 1a from the finger groove 5 side. become.

A bolt hole 9 is provided in the base 2 in parallel with the striker fitting hole 3 so that the base 2 can be screwed onto a rear quarter inner panel 10. By attaching the base 2 in this manner, the striker 1 is fixed in the direction in which it moves forward and backward relative to the cam of the rear seat.

A coil spring 4 installed around the end of the striker 1 protruding on the side opposite to the side where the finger groove is installed in the base 2 has one end hooked to a spring locking hole 11 provided at the end of the striker, and the other end attached to the base 2. It is hooked into the spring locking hole 13 of the bracket 12 provided on the side opposite to the side where the finger groove of No. 2 is installed.

A cam device that engages with such a retractable striker has a rear backlock assembly 17 built into the rear end of the rear seat 14 that includes a rotatable cam 15 and a cushion 16 for vibration isolation when locked. The operating bar 18 is structured so that it can be hooked to the striker 1 by pushing and pulling an operating knob 19 protruding from the top of the seat.

In this embodiment, with the above configuration, as shown in FIG. 5, when changing the position of the rear seat 14 from the upright state (position A in the figure) to the forward folded state (position B in the figure) is the operation knob 19.
Operate to remove the cam 15 hooked to the striker 1 and tilt the rear seat 14 forward.

In addition, when changing the position of the rear seat 14 from the upright position (position A in the figure) to the fully reclined state (position C in the figure), operate the operation knob 19 to engage the striker 1. Remove the stopped cam 15 and hold the grip part 1a of the striker 1.
Press to fit the gripping part 1a into the gripping part fitting hole 6 of the base 2 against the biasing force of the coil spring 4. The striker 1 is suppressed by the clamping force of the striker protrusion prevention protrusion 8 of the base 2,
A striker 1 is housed in a base 2 against the biasing force of a coil spring 4. When the striker 1 is housed in the base 2, there is no obstacle to tilting the rear seat 14 backward, and the rear seat 14
Push back to collapse to the fully reclined position. Conversely, when returning to the standing position, the rear seat 14
Raise it from the fully reclined position and
When the grip part 1a of the striker 1 is pulled out from the base 2 by inserting a finger into the finger groove 5 and pulling out the grip part 1a from the base 2 against the clamping force of the striker protrusion 8, the biasing force of the coil spring 4 is removed. This allows the striker 1 to protrude from the base 2 toward the passenger compartment, and after the striker 1 protrudes from the base 2, the operation knob 19 is operated to engage the cam 15 with the striker 1, and the rear seat 14 is placed in an upright position. Can be fixed. When the cam 15 engages the striker 1, the anti-vibration cushion 16 suppresses the striker 1 to eliminate backlash after the striker 1 engages.

As a result of the above explanation, in this embodiment, the striker 1 can be stored in the base 2 that is screwed onto the rear quarter inner panel 10, so new equipment on the rear seat side, a cutout that penetrates from the back side to the front side, etc. There is no need to provide a relief for the striker 1, and a simple lock system capable of full reclining can be realized. Therefore, since the rear seat back can be used as is, it can be changed to a fully reclining type at a low cost. Since the striker 1 is stored in the base 2 when fully reclined, there is no protruding feeling and there is no danger. Furthermore, it is easy to increase the number of strikers 1 attached to provide multi-stage reclining.

(Effects of the invention) As described above, the present invention makes it possible to store the striker used in the locking system of an automobile seat in the base attached to the vehicle body, thereby realizing a simple locking system that can fully recline. Since the current rear seat back can be used as is, conventional products can be easily and inexpensively changed to a full reclining type. By attaching a plurality of these retractable strikers, it can be changed to a multi-stage reclining type.
