Seat slide position detection device for vehicle
View Patent ↗A seat slide position detection device for a vehicle includes: a fixed rail attached to a vehicle floor; a movable rail supported to the fixed rail slidably in a longitudinal direction of the fixed rail; a detected portion disposed in a predetermined area of the fixed rail extending in the longitudinal direction; and a position sensor attached to the movable rail and having a sensor detector in a position of the position sensor opposed to the detected portion. The position sensor includes a protrusion attached to the movable rail with an extremity portion of the protrusion in contact with the movable rail.
1. A seat slide position detection device for a vehicle, comprising:
a fixed rail attached to a vehicle floor;
a movable rail supported to the fixed rail slidably in a longitudinal direction of the fixed rail;
a detected portion disposed in a predetermined area of the fixed rail extending in the longitudinal direction;
a seat cushion frame fixedly held by the movable rail; and
a position sensor attached to the movable rail via the seat cushion frame and having a sensor detector in a position of the position sensor opposed to the detected portion, wherein the position sensor comprises a protrusion with an extremity portion in contact with the movable rail,
wherein the position sensor has an extended portion,
wherein the extended portion extends in a vertical direction towards the fixed rail, and
wherein the protrusion is provided on the extended portion and protrudes toward the movable rail in a lateral direction.
2. The seat slide position detection device for vehicle according to claim 1 , wherein the position sensor has one end portion fixedly held by the movable rail via the seat cushion frame and an other end portion locked by the seat cushion frame to form a positioning section.
3. The seat slide position detection device for vehicle according to claim 1 ,
wherein the detected portion is disposed on a top surface of an engagement portion of the fixed rail,
wherein the top surface is substantially opposite a bottom surface of the engagement portion, and
wherein the bottom surface engages with the movable rail.
4. The seat slide position detection device for vehicle according to claim 1 , wherein the protrusion is in line contact with a side surface of the movable rail.
5. The seat slide position detection device for vehicle according to claim 1 ,
wherein the detected portion is disposed on a top surface of an engagement portion of the fixed rail with the movable rail,
wherein the top surface is substantially opposite a bottom surface of the engagement portion,
wherein the bottom surface engages with the movable rail,
wherein the sensor detector is provided on a lower end of the extended portion,
wherein the lower end is substantially opposite to an upper end of the extended portion,
wherein the upper end is attached to the movable rail, and
wherein the detected portion and the sensor detector face each other in the vertical direction.
6. A seat slide position detection device for vehicle, comprising:
a fixed rail attached to a vehicle floor;
a movable rail supported to the fixed rail slidably in a longitudinal direction of the fixed rail;
a detected portion disposed in a predetermined area of the fixed rail extending in the longitudinal direction;
a seat cushion frame fixedly held by the movable rail; and
a position sensor attached to the movable rail via the seat cushion frame and having a sensor detector in a position of the position sensor opposed to the detected portion, wherein the position sensor comprises a protrusion with an extremity portion in contact with the movable rail,
wherein the position sensor has one end portion fixedly held by the movable rail via the seat cushion frame and an other end portion locked by the seat cushion frame to form a positioning section,
wherein the one end portion of the position sensor is fixedly held by the movable rail via the seat cushion frame with a bolt, and
wherein a position of the positioning section is adjusted relative to an end edge of the seat cushion frame by using a rotation center of the bolt as a reference.
7. The seat slide position detection device for vehicle according to claim 1 , wherein the lateral direction is 90° from the longitudinal direction.
8. The seat slide position detection device for vehicle according to claim 1 , wherein the vertical direction is 90° from the lateral direction and the longitudinal direction.
9. The seat slide position detection device for vehicle according to claim 6 ,
wherein the detected portion is disposed on a top surface of an engagement portion of the fixed rail,
wherein the top surface is substantially opposite a bottom surface of the engagement portion, and
wherein the bottom surface engages with the movable rail.
10. The seat slide position detection device for vehicle according to claim 6 , wherein the protrusion is in line contact with a side surface of the movable rail.
