A reclining device (A) for appropriately adjusting an inclination of a seat back with respect to a seat cushion includes a worm (4) rotatably mounted on the seat cushion, a helical gear (6) mounted on the seat back and held in engagement with the worm (4), and a lock cam (14) for locking the worm (4) and the helical gear (6) or releasing the lock of the worm (4) and the helical gear (6). Both the worm (4) and the helical gear (6) have a lead angle greater than a friction angle. A lock plate (16) having a locking protrusion (16a) formed therewith is interposed between the worm (4) and the lock cam (14). The lock cam (14) is operable to press the lock plate (16) against the worm (4) to engage the locking protrusion (16a) with a portion of the worm (4), thereby locking the worm (4) and the helical gear (6).

Reduces backlash and clearance in a thrust direction of a worm when engaging a seat back to more securely prevent the generation of abnormal noise that before. A movable bearing 12 is pressed by cams 21, 22 that are pressing members, when the seat back is stopped at a predetermined angle, to approach a worm wheel 5. A ball 14 disposed in a recess 12a of the movable bearing 12 moves slightly along an inner surface of the recess 12a so a worm 4 is pressed to the worm wheel 5 side and pressed to the fixed bearing 11 side, and a latch member 23 that is a engaging member engages the worm 4 to inhibit rotation of the worm wheel 5 thereby securely holding that state. Since the movable bearing 12 moves to the worm wheel 5 side, the substantial movement range of the ball is wider compared to a structure that supports a ball only at a fixed bearing, and the range of displacement of the worm 4 by being pressed by the ball is substantially larger.

The invention relates to a drive device (31) comprising an electric drive motor (2), a housing with preferably a housing cover (39), at least one shaft (36) that is powered by the drive motor and compensating means for compensating the axial play of the shaft. Said compensating means contain at least one axially elastic, deformable elastomer element (53) comprising at least one contact surface. The invention is characterized in that the contact surface(s) (53) has/have a PTFE, PET or corresponding coating.
摘要:
A recliner adjuster for appropriately adjusting an inclination of a seat back with respect to a seat cushion includes a worm gear rotatably mounted on the seat cushion and a helical gear mounted on the seat back via auxiliary locking mechanism and held in engagement with the worm gear. During normal use, the seat back is held at a predetermined angle with respect to the seat cushion by the engagement of the helical gear with the worm gear. When a load greater than a predetermined value is inputted to the seat back, the auxiliary locking mechanism acts to hold the seat back at the predetermined angle with respect to the seat cushion.
