Output reduced by a reduction mechanism A contained within a tube type motor body 5 is transmitted to a threaded shaft 13, and a nut 15 having a wing element 15a for transforming rotation of the threaded shaft 13 to propulsion is threadingly engaged with the threaded shaft 13. Then, reduction and boost is made between a linear groove 16a of a guide member 16 secured to an inner wall of the body 5 and the rotation is transmitted to the body 5 by this rotational force, thereby an arm 17 provided on the body 5 is swung so that a base 3 is adjusted upwardly and downwardly about bearing members 2, 2a mounted on slide rails 1, 1. Owing to this arrangement, since a smaller installation space can be achieved, the apparatus can be made small in size and commonly used for various types of automotive vehicles. Moreover, the apparatus can be unitized. In addition, a high torque transmission is made possible by reduction and boost.

Power seat adjusting apparatus

A reclining device for vehicle seats utilizes a differential reduction gear (A) and a small size high speed motor (27) as a drive source, wherein one gear (10) having a plurality of slots (15) positioned radially outwardly from the axis of the gear is between another gear (16) having a corresponding number of slots (20) in alignment with the slots (15) in the one gear and a bracket (22) associated with the other gear (16) and held in position by rivets (12,21) through the aligned slots in the two gears to thereby regulate the adjustment range of the reclining angle. The motor output shaft (27a) and reduction gear (A) are connected by a resilient joint (35), a resilient member (32) is interposed between the motor and coupling (33) or between the coupling and reduction gear (A) to prevent oscillation and noise, and a coiled spring (43) acts on one end of the worm shaft (30a) of the reduction gear to prevent play between a worm (30 ) and worm gear (29).

Reclining device

There is provided an automotive power seat assembly comprising a movable seat cushion, a backrest tiltable relative to the seat cushion, a reclining mechanism for reclining the backrest, seat rail means including upper rails secured to the seat cushion and lower rails secured to the body of the automobile, a motor for driving the reclining mechanism and a current control circuit for controlling the flow of current through the motor.
