Abstract

A seat sliding mechanism includes a lower rail, an upper rail, a position sensor and a sensor bracket. The lower rail is provided on a side of a vehicle floor. The upper rail is provided at a lower part of a seat body and is slidably supported by the lower rail along front and rear directions. The position sensor is provided on the upper rail and detects a position along front and rear directions. The sensor bracket is provided on the lower rail and its proximity state to the position sensor is to be detected. The sensor bracket includes a base, a detected portion and a supporting portion. The base is fixed to a bottom of the lower rail. The detected portion is detected by the position sensor. The supporting portion supports the detected portion.

Claims

1. A seat sliding mechanism comprising:

a lower rail which is provided on a side of a vehicle floor;

an upper rail which is provided at a lower part of a seat body and which is slidably supported by the lower rail along front and rear directions;

a position sensor which is provided on the upper rail and which detects a position along front and rear directions; and

a sensor bracket which is provided on the lower rail and whose proximity state to the position sensor is to be detected,

wherein the sensor bracket includes;

a base which is fixed to a bottom of the lower rail;

a detected portion which is detected by the position sensor; and

a supporting portion which supports the detected portion at an obliquely upward and forward position or an obliquely upward and rearward position with respect to the base.

2. The seat sliding mechanism according to claim 1, wherein

the position sensor includes a detection portion which detects the detected portion of the sensor bracket which is to be positioned below the detection portion, and

the supporting portion has a shape having a downward cut out at a part nearer to the base from an end of the detected portion nearer to the base.

3. The seat sliding mechanism according to claim 2, wherein

the supporting portion has a shape having a cut out extending vertically downward with respect to the detected portion from the end of the detected portion nearer to the base.

4. The seat sliding mechanism according to claim 1, wherein

a bead is formed on the supporting portion.

5. The seat sliding mechanism according to claim 4, wherein the bead is formed so as to extend from the base along a direction toward the detected portion.

6. The seat sliding mechanism according to claim 1, wherein the base includes a flange formed at a front end or a rear end thereof.

7. The seat sliding mechanism according to claim 6, wherein

the base has a fixing hole for being fixed to the lower rail, and

the flange is formed in a range including a portion of the fixing hole on a side of the supporting portion when seen along front and rear directions.

8. The seat sliding mechanism according to claim 6, wherein

the bead formed on the supporting portion and the flange formed on the base are formed so as to overlap with each other when seen along front and rear directions.

9. The seat sliding mechanism according to claim 1, wherein

the sensor bracket is provided on the lower rail such that the detected portion is higher than the lower rail.
