Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, a case where the lock device 1 is applied to a seat reclining device 2 for a vehicle will be described. figure 1 It is a perspective view showing the frame of the seat reclining device 2 according to the present embodiment.

[0032] 1. Overall configuration of the seat reclining device 2

[0033] Such as figure 1 As shown, the seat reclining device 2 has: a seat back frame 3 constituting the frame of the seat back, a seat cushion frame 4 constituting the frame of the seat cushion, and the seat back frame 3 and the seat seat. The locking device 1 of the connection part between the pad frames 4 , the operating lever 5 and the lever shaft 6 as the operating part of the locking device 1 . Furthermore, when the locking device 1 is in the locked state, the angle of the seat back frame 3 relative to the seat cushion frame 4 is fixed. On the other hand, ...

Abstract

A lock device enabling the suppression of the binding of lock members during unlocking operation and the suppression of a variation in the engaging timings of the plurality of lock members during locking operation when the plurality of lock members are operated by a cam member. The guide parts (14) of a lower guide (15) comprise a plurality of cam guide faces (14a) disposed apart from each other along the circumferential direction. A cam (13) comprises a plurality of guided faces (13b) in contact with the plurality of cam guide faces (14a) in a phase released state. The guided face (13b) positioned in the eccentric direction of the cam (13) by the energizing force of a lock spring (16) is extended to a released phase side relative to the other guided faces (13b).

Description

technical field [0001] The present invention relates to a lock device capable of engaging and releasing two members, and a seat reclining device using the lock device for adjusting the angle of a seat cushion and a seat back. Background technique [0002] As a technology related to a lock device used in a seat reclining device, for example, Patent Document 1 below discloses the following technology. The locking device is configured substantially the same as the embodiment of the present invention described later. That is, if Figure 7 and Figure 8 As shown, a lower conductor 51 , an upper gear 52 , a collar 53 , three pawls 54 , a cam 55 , and a spring 56 are provided. The upper gear 52 has internal teeth 52a formed on the inner peripheral surface. On the other hand, external teeth 54 a that engage with the above-mentioned internal teeth 52 a are formed on the outer peripheral end surfaces of the three pawls 54 . The cam 55 oscillates between the locked phase and the re...
