Abstract

In right and left upper rails in a power sliding apparatus of a conveyance seat, openings to receive gear boxes are formed, respectively. The gear boxes are attached to the right and left upper rails via the openings, respectively. The opening in one of the right and left upper rails is closed with a motor fixing bracket to fix a motor unit.

Claims

1. A power sliding apparatus of a conveyance seat comprising:

right and left upper rails;

right and left lower rails;

a motor unit which is fixed to one of the right and left upper rails;

a motor fixing bracket to fix the motor unit to the one upper rail; and

transmission shafts and gear boxes to transmit a rotational force of a motor constituting the motor unit to ball screws or ball nuts attached to the lower rails or the upper rails,

wherein when the rotational force of the motor is transmitted to the ball screws or the ball nuts, the right and left upper rails slide relatively to the right and left lower rails,

in the right and left upper rails, openings to receive the gear boxes are formed, respectively,

the gear boxes are attached to the right and left upper rails via the openings, respectively, and

the opening in one of the right and left upper rails is closed with the motor fixing bracket.

2. The power sliding apparatus of the conveyance seat according to claim 1, further comprising:

a reinforcing bracket which closes the opening in the other upper rail,

wherein the motor fixing bracket is fastened to the reinforcing bracket.

3. The power sliding apparatus of the conveyance seat according to claim 2,

wherein the motor fixing bracket is integrally formed with the reinforcing bracket to serve as the reinforcing bracket.

4. The power sliding apparatus of the conveyance seat according to claim 1,

wherein the motor unit is fixed to the motor fixing bracket via an attaching bracket secured to the motor itself, and

an edge of the attaching bracket is attached to the motor fixing bracket by bending attaching pieces formed in the motor fixing bracket.
