Description

DETAILED DESCRIPTION OF THE INVENTION <<Technical Field of the Invention>> The present invention relates to a door trim for an automobile, and particularly to a door trim for an automobile in which a cushion side component is provided on the side.

≪Prior art and its problems≫ In narrow passenger cars, members that make up the side part of the seat cushion, such as side supports and armrests, or side supports and armrests, are integrated on the side of the door trim adjacent to the seat cushion. Installing parts. Also,
This member (hereinafter referred to as a side component) becomes a nuisance when getting on and off the vehicle.

In order to eliminate such problems, for example,
As seen in Publication No. 57-131342, by making the side component members slidable back and forth, and by hooking the hook provided at the rear end of the side component member to the seat bag, the side component member can be moved to the rear end position. There are some devices that allow the side component to be moved forward by holding the door in place and unlocking the hook by operating the door lock or door handle.

However, with this configuration, the lock/unlock mechanism is linked to the door lock or door handle, making the mechanism complicated and difficult to install.

<<Purpose of the Invention>> This invention adds a simple mechanism to the door trim, which locks the cushion side component provided on the side of the door trim to the groove side when the door is closed, and releases the lock when the door is opened. With the goal.

<<Structure of the Invention>> In order to achieve the above object, the present invention includes a side component member provided on the side of an automobile door trim so as to be slidable back and forth, and a side component member provided on the inside of the door trim,
A spring means for always biasing the side component in the forward direction; a lock member for locking the side component in the backward position; and a lock release pin integral with the lock member and protruding from the lower side of the door trim facing the body. , consists of a spring means that biases the pin toward the protruding side, and when the door is closed, the pin contacts the body and retracts, thereby locking the side component in the retreated position, and also prevents the pin from moving when the door is opened. It is characterized in that the lock is released by protrusion.

<<Embodiments of the Invention>> Figs. 1 and 2 show the external structure of a door trim to which this invention is applied, Figs. 3 and 4 show the operating states of the slide mechanism and the lock mechanism, respectively, and Figs. FIG. 6 is a detailed view of the slide and lock mechanism.

In FIG. 1, a door trim 3 is attached to the inner surface of a door panel 2 adjacent to a seat 1. There is a shallow groove 4 in the front and rear direction in the center of the door trim 3.
is formed, and an armrest 5 is attached to this shallow groove 4 so as to be slidable back and forth.

A pair of guide holes 4a are formed in the shallow groove 4, and a pair of guide pins 5a protruding from the inner side of the armrest 5 to be engaged with each guide hole. Furthermore, an L-shaped slide pin 6 is fixed to the center of the inner side of the armrest 5, as shown in FIGS. 3 to 5.

By suspending a tension spring 8 between the slide pin 6 and a terminal 7 fixed to the inside of the door trim 3, the armrest 5 is constantly urged in the forward direction along the guide hole 4a. At the rear of the slide pin 6, the inner surface of the door trim 3 has a third
A bracket 9 is fixed as shown in FIGS. A lock member 10 is provided on the bracket 9, and the slide pin 6 is inserted into the lock hole 10a. The center of the locking member 10 can swing around a fulcrum pin 11 inserted through the bracket 9, and is supported by a compression spring 12 having one end fixed to the bracket 9 and the other end abutting against the locking member 10. , is always biased in the lock release direction.

A lock pin 14 is provided at the bottom of the lock member 10 via a link lever 13. The lock pin 14 passes through a guide bush 16 provided at the bottom of the door trim 3 and projects from the side surface of the bottom of the door trim 3.

FIG. 1 shows a state in which the door panel 2 is closed and the side surface of the door trim 3 approaches the seat. At this time, the lock pin 14 is in contact with the body surface of the automobile and retracted into the door trim 3 against the biasing pressure of the spring 12. As a result, the lock member 10 rotates in the direction of arrow A (see FIG. 5) about the fulcrum pin 11 as a fulcrum.

As a result, the lock hole at the upper end engages with a lock pawl 6a provided on the slide pin 6, and the arm rest 5 is held in the retracted position shown in FIG. 1 against the biasing pressure of the tension spring 8.

From this state, as shown in Figure 2, the door panel 2
When opened, the lock pin 14 protrudes as shown by arrow B, rotates the lock member 10 in the direction of arrow B (see FIG. 5), and releases the engagement with the lock pawl 6a.

As a result, the slide pin 6 is moved forward by the biasing pressure of the spring 8, and the armrest 5 is moved in the forward direction shown by arrow C in FIG.

When the door is opened and then closed again, the armrest 5 is in the forward position shown in FIG.
When moved to the rear side as indicated by arrow A in Figure 1,
The lock pawl 6a of the slide pin 6 is inserted into the lock hole 1 again.
0a and is automatically locked. When locked, the lock pawl 6a is always biased toward the protruding side by a spring 6c, as shown in FIG.
It retracts at one end against the biasing pressure of the lock hole 10a, and the moment it passes through the lock hole 10a, it projects again and maintains the locked state. Further, 6b is a stopper for retracting the armrest 5, which is fixed to the slide pin 6 so as to face the lock pawl 6a.

In the embodiment, the armrest is attached to the side of the door trim so that it can be slid back and forth, but the present invention is not limited to this, and it is also possible to attach a side support or a member in which the side support and the armrest are integrated. Of course it's a good thing.

<<Effects of the Invention>> As explained above, the present invention allows armrests and other cushion side components to be locked in the retreated position when the door is closed, and the locks are automatically released when the door is opened. Since the side components can be automatically moved to the forward position, the structure is much simpler and easier to install compared to conventional door handles, door locks, etc. that are linked to release the lock. Since it is limited to the inside of the door trim, assembly is easy.
