Problems solved by technology

[0009] When the housing member 508 is deformed, there is a risk that the locking pin 502 slips out of the engagement groove 504, resulting in disengagement.
Although the overall thickness of the shell member 508 can be increased simply by increasing the strength, this will lead to an increase in weight and cost.

Embodiment Construction

[0060] Hereinafter, the seat lock device 10 according to the embodiment will be specifically described with reference to the drawings. In addition, this invention is not limited to this embodiment.

[0061] Such as figure 1 and figure 2 As shown, the seat lock device 10 of the present embodiment is applied to the left and right seats 12 of the vehicle, respectively. A part of the seat lock device 10 is covered by a cover 11 . The seat 12 includes a seat cushion 12a as a seat surface and a seat back 12b as a backrest. The seat back 12b rotates around the seat back rotation shaft 13, and can be tilted and switched to an upright posture for normal sitting and a forward tilted posture for easy loading. In addition, the upright posture can be switched between the standard first upright posture and the further inclined second upright posture using the mechanism of the seat lock device 10 . figure 1 In the figure, the first upright posture of the seat back 12b is shown by a s...

Abstract

The present invention provides a seat lock device capable of suppressing deformation when a lateral load is applied from a lock pin and a pressing force is applied. The seat locking device (10) keepsthe seat back of the vehicle in a locked state. The seat lock device (10) has a hook member (26) provided with an engagement groove (26a) that engages with a lock pin (14) that enters from the rear; arotation shaft (26c) pivotally supporting the hook member (26) near the front end to rotate freely; an outer casing (20) used for fixing the rotation shaft (26c); a locking pin entry groove (20i) formed in the outer casing (20) for the locking pin (14) to enter; a plurality of fixing portions for fixing the outer case (20) to the frame (18) of the seat back (12b). Each fixing portion includes a mounting piece (20g) protruding inward from a rear surface (20c) of the outer case (20).

Description

technical field [0001] The present invention relates to a seat lock device for maintaining a reclinable seat back in a locked state. Background technique [0002] A vehicle seat has a seat cushion as a seat surface and a seat back as a backrest, wherein the seat back can be tilted and switched to an upright posture for normal seating and a forward tilting position for carrying cargo. posture. In the upright posture for seating, a seat lock device provided on the seat back (for example, see Patent Document 1) is engaged with a lock pin fixed to the vehicle body to maintain a locked state and stabilize it. In addition, there is a seat lock device that switches the erect posture between two levels using an internal mechanism of the seat lock device. When mainly considered from an exterior design point of view, the seat locking mechanism is mostly covered by a cover. [0003] Such as Figure 9 As shown, the basic structure of the seat locking device 500 in the prior art inclu...
