Seat sliding apparatus for a vehicle
First Claim
1. A seat sliding apparatus for a vehicle, comprising:
- a first pair of rails fixed to either one of a floor of a vehicle and a seat in the vehicle;
a rail structure including a second pair of rails fixed to the other one of the floor and the seat, the second rails being connected to the first rails in a manner movable relative to the first rails in a seat forward-rearward direction;
a pair of nut members, wherein each of the nut members is fixed to one of the first rails, respectively;
a pair of screw shafts, wherein each screw shaft is rotationally supported by the one of the second rails and threaded to one of the nut members, respectively, the screw shafts rotating relative to the corresponding nut members to move the second rails relative to the first rails in the seat forward-rearward direction;
a speed reducer-equipped motor connected to the two screw shafts through a transmission mechanism to rotate the screw shafts, the speed reducer-equipped motor including a motor, a gear mechanism, which is connected to a rotary shaft of the motor to reduce the speed of rotation of the motor, and a gear housing that rotationally supports the gear mechanism and is fixed to the rail structure such that the axis of an output shaft of the gear mechanism extends in a seat width direction; and
a manipulation switch electrically connected to the equipped motor for actuating the speed reducer-equipped motor, the manipulation switch having a manipulating portion fixed to the gear housing and exposed at a forward end of the seat;
a rotation sensor for detecting rotation of the motor;
a control circuit that controls rotation of the motor based on the detected rotation;
a circuit case for accommodating the rotation sensor and the control circuit;
wherein the circuit case is fixed to the gear housing; and
wherein the manipulation switch is fixed to the gear housing through the circuit case and electrically connected to the motor through the control circuit.

Abstract
Disclosed is a seat sliding apparatus for a vehicle, the apparatus provided with a pair of lower rails fixed to the vehicle floor and a pair of upper rails fixed to a vehicle seat. The seat sliding apparatus causes screw shafts supported at the upper rail to rotate relative to nut members fixed to the lower rails and the upper rails to move relative to the lower rails in the seat forward-rearward direction. A speed reducer-equipped motor comprises a motor, a gear mechanism, and a gear housing. The gear housing is designed so that the axis of the output shaft of the gear mechanism extends in the seat width direction. A manipulation switch comprises a manipulating portion fixed to the gear housing such that the operation switch is exposed at a forward end of the seat.
