Abstract

An apparatus of tilting a seat cushion of a vehicle, includes a tilting motor, a pinion gear, a sector gear, and a tilting link which perform the tilting operation of the seat cushion and exert a binding force in a tilted state of the seat cushion and are provided to be connected to both of one side and the other side of a seat cushion frame, and has two sector gears positioned on left and right sides and connected to each other by a connection bar so that, by strengthening a binding force of the front portion of the seat cushion, it is possible to secure the safety of passengers in the event of a collision.

First claim

What is claimed is:

1. An apparatus of tilting a seat cushion of a vehicle, the apparatus comprising:
a tilting motor, a pinion gear coupled to the tilting motor, and a sector gear engaged to the pinion gear, wherein the tilting motor, the pinion gear, and the sector gear are configured to implement a tilting operation of the seat cushion and are provided to be connected to left and right sides of a seat cushion frame, respectively,
wherein, when the tilting motor is operated, a tilting operation of the seat cushion is implemented as a front end portion of the seat cushion frame is rotated to be moved up and down about a rear hinge shaft disposed at a rear side of the seat cushion frame,
wherein the pinion gear is coupled to the tilting motor positioned on each of the left and right sides of the seat cushion frame, and
wherein the sector gear is engaged with the pinion gear on each of the left and right sides of the seat cushion frame.

2. The apparatus of claim 1 , further including:
a motor bracket, a front set bracket, a rear set bracket, and a seat rail,
wherein the tilting motor is in plural,
wherein the tilting motors are positioned on each of the left and right sides of the seat cushion frame, respectively and are coupled to the motor bracket,
wherein the motor bracket is coupled to the front set bracket and the rear set bracket in a front and rear direction of the vehicle, and
wherein the front set bracket and the rear set bracket are coupled to the seat rail to be spaced from each other in the front and rear direction.

3. The apparatus of claim 1 , further including:
a pair of tilting links rotatably connecting the sector gear to the seat cushion frame on the left and right sides of the seat cushion frame.

4. The apparatus of claim 1 , wherein the sector gear is in plural, and wherein the apparatus further includes:
a connection bar extending below the seat cushion frame in a left and right direction of the seat cushion and including first and second end portions provided to connect the sector gears.

5. The apparatus of claim 4 ,
wherein the sector gears include a first sector gear and a second sector gear, and
wherein the connection bar is provided between the first sector gear and the second sector gear positioned on the left and right sides of the seat cushion frame.

6. The apparatus of claim 5 , wherein positions where the first and second end portions of the connection bar are coupled to the sector gears are a concentrically same position.

7. The apparatus of claim 4 ,
wherein a connection bar mounting bracket is fixedly coupled to an internal side surface of the sector gears; and
wherein the first and second end portions of the connection bar are fixedly coupled to the connection bar mounting bracket.

8. The apparatus of claim 4 ,
wherein a connection bar coupling hole is formed to pass through the sector gears in the left and right direction, and
wherein the first and second end portions of the connection bar are inserted into the connection bar coupling hole to be engaged with the sector gears.

9. An apparatus of tilting a seat cushion of a vehicle, the apparatus comprising:
a tilting motor, a pinion gear coupled to the tilting motor, and a sector gear engaged to the pinion gear, wherein the tilting motor, the pinion gear, and the sector gear are configured to implement a tilting operation of the seat cushion and are provided to be connected to left and right sides of a seat cushion frame, respectively,
wherein, when the tilting motor is operated, a tilting operation of the seat cushion is implemented as a front end portion of the seat cushion frame is rotated to be moved up and down about a rear hinge shaft disposed at a rear side of the seat cushion frame, and
wherein the apparatus further includes a motor bracket, a front set bracket, a rear set bracket, and a seat rail,
wherein the tilting motor is in plural,
wherein the tilting motors are positioned on each of the left and right sides of the seat cushion frame, respectively and are coupled to the motor bracket,
wherein the motor bracket is coupled to the front set bracket and the rear set bracket in a front and rear direction of the vehicle, and
wherein the front set bracket and the rear set bracket are coupled to the seat rail to be spaced from each other in the front and rear direction.

10. An apparatus of tilting a seat cushion of a vehicle, the apparatus comprising:
a tilting motor, a pinion gear coupled to the tilting motor, and a sector gear engaged to the pinion gear, wherein the tilting motor, the pinion gear, and the sector gear are configured to implement a tilting operation of the seat cushion and are provided to be connected to left and right sides of a seat cushion frame, respectively,
wherein, when the tilting motor is operated, a tilting operation of the seat cushion is implemented as a front end portion of the seat cushion frame is rotated to be moved up and down about a rear hinge shaft disposed at a rear side of the seat cushion frame, wherein the sector gear is in plural, and
wherein the apparatus further includes a connection bar extending below the seat cushion frame in a left and right direction of the seat cushion and including first and second end portions provided to connect the sector gears,
wherein a connection bar mounting bracket is fixedly coupled to an internal side surface of the sector gears; and
wherein the first and second end portions of the connection bar are fixedly coupled to the connection bar mounting bracket.
