Problems solved by technology

[0007] However, as the size of the latch in the rotational direction becomes larger, the amount of rotation (rotation angle range) required for the latch increases, so the seat lock device also becomes bulky.
The seat lock device is required to be further reduced in size, but the need to increase the size of the latch in the rotational direction becomes a factor hindering the miniaturization of the seat lock device

Embodiment Construction

[0019] Hereinafter, a specific embodiment of a seat in which a seat lock device is provided in a rear portion of a vehicle will be described.

[0020]

[0021] Such as figure 1 As shown, the rear seat 10 has a seat cushion 11 for the passenger to sit on, and a seat back 12 for the passenger to lean on the back. The seat back 12 is provided so as to be rotatable about the lower end thereof relative to the seat cushion 11 . Seat back 12 in figure 1 The upright position shown in solid line is the same as figure 1 Move between the forward lean positions indicated by the dash-dotted line in the middle.

[0022] The upper side surface of the seat back 12 is provided with a seat lock device 13 . When the seat back 12 is in the upright position, the seat lock device 13 engages with a U-shaped striker 14 provided on the vehicle body to maintain the posture of the seat back 12 . That is, the seat 10 is locked to the vehicle body. By pulling the wire 15 connected to the seat lock...

Abstract

This seat lock device comprises a base that is provided to one of a seat and a vehicle body and has a slot part that is structured so as to receive a striker, said striker being provided to the otherof the seat and the vehicle body; a case that is provided facing the base and has a slot part that is structured so as to receive the striker; a hook that is rotatably provided between the base and the case and operates together with at least the slot part of the case to create a locked state in which the striker is sandwiched; a pole that is rotatably provided between the base and the case and holds the hook in the locked state by engaging with a peripheral surface of the hook; and a cam that is rotatably provided between the base and the case and pushes the hook, which is held in a locked state, in a locking direction, wherein a section of the hook and a section of the pole overlap one another in the axial direction thereof.

Description

technical field [0001] The present invention relates to a seat lock device for locking a seat of a vehicle to a vehicle body. Background technique [0002] For example, the seat locking device of Patent Document 1 includes: a base member provided with an insertion groove for receiving the striker; The claw that is held in the locked state, and the cam plate that applies a pressing force in the locking direction to the latch that is held in the locked state. The latch, claw, and cam plate are each supported rotatably relative to the base member. In addition, the latch has a restraint groove that engages with the striker inserted into the groove. Depending on the difference in the rotational position of the latch, the restraint groove becomes an open state or a closed state within the fitting groove. The latch is always forced towards the opening direction of the restraint slot, ie clockwise. The jaws and cam plate are always respectively biased counterclockwise. [0003]...
