Embodiment Construction
[0040] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0041] Figure 10 It is a side view showing a vehicle seat 1 provided with a vehicle seat reclining device according to an embodiment of the present invention. like Figure 10 As shown, a pair of seat slide mechanisms 3 that support the seat 1 slidably in the vehicle front-rear direction are provided on the vehicle floor 2 . The pair of seat slide mechanisms 3 are arranged in parallel at intervals in the vehicle width direction. A pair of seat slide mechanisms 3 supports a seat cushion 4 forming a seating surface of the above-mentioned seat 1 . At the rear end of the seat cushion 4, by figure 1 The shown pair of known locking mechanisms 20 is coupled to a seat back 5 for forming the back portion of the above-mentioned seat 1 so as to be able to tilt and move in the vehicle front-rear direction.
[0042] The inclination movement angle of the seat back 5 relative t...

A seat reclining device for a vehicle is disclosed that includes a lock mechanism and a memory mechanism. The seat reclining device is arranged between a seat cushion frame and a seat back frame, and includes a control shaft associated with operation of an unlock operation lever. The lock mechanism includes a rotating body, which is secured to the seat back frame and is supported to be freely rotatable with respect to the base body. The memory mechanism includes a plate portion having an engaging portion, a holding bracket, which is freely rotatable about a rotational axis that is the same as the control shaft, a memory pole, a restricting portion, which restores the holding bracket to a predetermined initial position, a lever member, which is rotated in accordance with operation of the memory operation lever, and an engagement holding portion, which disengages the memory pole from the plate portion as the holding bracket is restored to the initial position.
Description
technical field [0001] The present invention relates to a vehicle seat reclining device provided with a memory mechanism capable of returning a seat back relative to a seat cushion to an angular position of the seat back before falling forward. Background technique [0002] As a vehicle seat reclining device, for example, a device described in Patent Document 1 is known. The seat reclining device for a vehicle includes a first cable connected to the memory operating lever, a lock mechanism, a lever member coaxial with the lock mechanism, a second cable connected to the lever member, and a memory gear attached to the back frame. , and a sector gear coaxial with the above-mentioned locking mechanism. When the first cable is pulled up by operating the memory operation lever, the second cable is pulled up as the lever member is rotated, whereby the memory gear meshes with the sector gear. The sector gear is held detachably from the seat cushion frame by the frictional force of...
