Power seat slide device
First Claim
1. A power seat slide device comprising:
- a stationary rail;
a movable rail axially slidably engaged with said stationary rail, said movable rail and said stationary rail being assembled to define therebetween an elongate tunnel which extends along a common axis of said stationary and movable rails;
a driven threaded shaft housed in said elongate tunnel and having both ends rotatably supported by said movable rail;
a nut received in said elongate tunnel and fixed to said stationary rail, said driven threaded shaft being operatively engaged with said nut so that rotation of said driven threaded shaft about its axis induces a longitudinal movement of said movable rail relative to said stationary rail;
a drive device mounted on said movable rail, said drive device having a drive shaft;
a gear mechanism arranged between said drive shaft and said driven threaded shaft for transmitting a power of said drive shaft to said driven threaded shaft;
a gear housing for housing therein said gear mechanism; and
a pair of holders secured to said movable rail, such that said gear housing is disposed between said holders, said holders having means to tightly clamp said gear housing therebetween and such that said gear housing and said holders are aligned along said driven threaded shaft.

Abstract
A power seat slide device includes a pair of parallel stationary rails and a pair of parallel movable rails axially slidably engaged with the stationary rails. The movable rail and the stationary rail are assembled to define therebetween an elongate tunnel which extends along a common axis of the stationary and movable rails. A threaded shaft is housed in the elongate tunnel and has both ends rotatably supported by the movable rail. A nut is received in the elongate tunnel and fixed to the stationary rail. The threaded shaft is operatively engaged with the nut so that rotation of the threaded shaft about its axis induces a longitudinal movement of the movable rail relative to the stationary rail. An electric motor is mounted on the movable rail and has a drive shaft. A gear mechanism is arranged between the drive shaft and the threaded shaft for transmitting a power of the drive shaft to the threaded shaft. A gear housing houses therein the gear mechanism. A pair of holders are secured to the movable rail with the gear housing placed therebetween for holding the gear housing.

13. A power seat slide device comprising:
-
a stationary rail; a movable rail axially slidably engaged with said stationary rail, said movable rail and said stationary rail being assembled to define therebetween an elongate tunnel which extends along a common axis of said stationary and movable rails; a threaded shaft housed in said elongate tunnel and having both ends rotatably supported by one of said stationary and movable rails; a nut received in said elongate tunnel and fixed to the other of said stationary and movable rails, said threaded shaft being operatively engaged with said nut so that rotation of said threaded shaft about its axis induces a longitudinal movement of said movable rail relative to said stationary rail; a drive device mounted on the rail by which said threaded shaft is supported, said drive device having a drive shaft; a gear mechanism arranged between said drive shaft and said threaded shaft for transmitting a power of said drive shaft to said threaded shaft; a gear housing for housing therein said gear mechanism; and a holder being secured to the rail by which said threaded shaft is supported, said holder having means to tightly clamp said gear housing, said holder and said gear housing being aligned along the common axis of said stationary and movable rails.
