Description

[Detailed Description of the Invention] This invention relates to a rear seat locking device for an automobile.

For rear seatbacks that are equipped with a folding member that rotates forward to allow the trunk to pass through within the outer frame member attached to the vehicle body, various methods are used to lock the foldable member to the vehicle body. A device has been devised. (For example, see Japanese Utility Model Application Publication No. 57-27132.) Among these locking devices, those in which a slider engages with a striker can be made thinner than other devices, so they are advantageous in terms of space. Although the invention is an improvement on this, the structure of the conventional example will first be explained with reference to FIGS. 1 to 3 as follows.

The rear seat bag 1 consists of an outer frame member 2 and a collapsible member 3 located within the outer frame member 2 that rotates forward to provide a trunk through-hole. The collapsible member 3 is the lower edge 3
a, and a locking device for the vehicle body member 5 is provided at the upper edge 3b.

That is, as shown in FIGS. 2 and 3, an outer frame member 2 is attached to a vehicle body member 5, and a striker 7 is fixed to the vehicle body member 5 below.
A frame 8 embedded in the collapsible member 3 in response to this
A slider 10 that slides in the E direction and a spring 12 that supports the slider 10 are inserted into the slider. Then, the slider 10 is inserted into the recess 3c provided in the collapsible member 3.
A knob 14 fixedly mounted is located.

Therefore, when the collapsible member 3 is pulled up and placed in place, the slider 10 protrudes along the E direction due to the bias of the spring 12 and is locked to the striker 7, and the collapsible member 3 is fixed to the vehicle body member 5. Ru. Also, if you put your finger on the knob 14 and push down the slider 10 against the bias of the spring 12, the slider 10
is removed from the striker 7, and the collapsible member 3 becomes able to rotate forward.

However, this locking device has the disadvantage that it is likely to become unlatched if the seatback is subjected to inertia due to its own weight or luggage in the trunk during sudden braking or a collision. That is, as shown in Fig. 4, when a forward load F due to inertia is applied to the seat back, a component force f is generated along the moving direction of the slider 10, and the striker 7 is deformed to the state 7' shown by the chain line. At the same time, the slider 10 is deformed to a state 10' shown by a chain line. In this way, the relative positions of the striker 7 and the slider 10 change and the meshing distance becomes smaller, which causes them to become disengaged.

The present invention was devised to eliminate this drawback, and includes a hook attached to a retractable member along the slider and engaged in a groove provided in the striker.
This is designed to prevent changes in relative position between the slider and the striker.

The structure of the present invention will be explained below using the embodiment shown in FIG.

This structure differs from the conventional structure shown in FIGS. 2 and 3 in that the hook 16 is fixed to the frame 8 along the slider 10, and the striker 7 has a concave groove in which the end 16a of the hook 16 engages. 7a is provided. That is, when the collapsible member 3 is pulled up and placed in a fixed position, even if a load F is applied and a component force f is generated as shown in FIG. Therefore, the relative positions of the collapsible member 3 and the striker 7 in the E direction do not change. Therefore, since the engagement between the striker 7 and the slider 10 does not become small, disengagement does not occur.

To release the locking device, hold the knob 14 fixed to the slider 10 and push it down to disengage the striker 7 and the slider 10, allowing the collapsible member to rotate forward. Therefore, if you simply tilt the collapsible member forward, the hook 16 fixed to the frame 8 will come out of the groove 7a of the striker 7, so you can release it by normal operation without requiring any special operation. .

As mentioned above, the present invention reliably locks the collapsible member of the seat bag in a stationary state.
It has a simple structure, is lightweight, and can be formed at low cost, so it has great practical value.
