A support shaft has an integral protrusion which is abuttingly engageable with an arcuate portion of a support panel for limiting rotation of the support panel relative to the support shaft. A protrusion is provided at each axial end of the support shaft, while an opening with a slit-like opening portion is provided on each side panel of a seat back frame. The protrusion at each axial end of the support shaft and the opening at each side panel are constructed and arranged so that each axial end is capable of passing through the opening only when the support shaft is held in a particular position. The support shaft is put out of the particular position when in use such that each axial end is prevented from slipping out of the opening.

Lumbar support for seat

A powered seat slide device including at least one pair of guide rails for slidably supporting a seat such that the position of the seat relative to a floor is adjusted frontwardly and rearwardly, comprises a drive motor causing a relative sliding movement of one of the guide rails to the other, through a driving mechanism employing a gear box fixed to the one of the rails to serve as a reduction gear transmitting rotation torque from the motor to a screw-threaded shaft which is fixed onto the one of rails and engaged with a nut member rigidly mounted on the other rail for rotation relative to the screw-threaded shaft, while reducing a motor speed and increasing torque created by the motor, a motor mounting bracket formed integral with the gear box, for directly connecting the motor to the gear box, and an opening provided in the side wall of the one of rails, for avoiding the interference between the motor assembly and the guide rails.
