1. A vehicle seat comprising:
- a seat cushion having a cushion pad deformable to be flexed when a seating load of an occupant is applied; and
a seating sensor disposed within the seat cushion and constructed to detect a seating position of the occupant;
wherein the seating sensor is configured as a push-in switch and can detect the seating position of the occupant when the seating sensor is pressed by the cushion pad; and
a fragile region interleaved between the seating sensor and the cushion pad at a pressure receiving region where a pressing force is applied to the seating sensor,wherein the fragile region has a rigidity lower than the cushion pad,wherein the seating sensor comprises a first electrode sheet positioned on a side of the cushion pad and a second electrode sheet positioned on a side opposite to the first electrode sheet, the first and second electrode sheets defining a space therebetween; and
wherein the space is positioned on a side opposite to the fragile region with respect to the first electrode sheet.

Abstract
A vehicle seat has a seat cushion having a cushion pad deformable to be flexed when a seating load of an occupant is applied. A seating sensor is disposed within the seat cushion for detecting a seating position of the occupant. The seating sensor is configured as a push-in switch and can detect the seating position of the occupant when the seating sensor is pressed by the cushion pad. A fragile region is interleaved between the seating sensor and the cushion pad at a pressure receiving region where the pressing force is applied to the seating sensor. The fragile region has rigidity lower than the cushion pad.

8. A vehicle seat comprising:
-
a seat cushion having a resiliently deformable cushion pad; a seating sensor mounted within the cushion pad and operable to detect a seating position of an occupant when the cushion pad is deformed by a seating load of the occupant; and an accidental operation preventing device constructed to prevent the seating sensor from being accidentally operated when the occupant is not seated on the vehicle seat, wherein; the cushion pad defines therein a sensor receiving space; the sensor receiving space has a first wall surface and a second wall surface opposed to each other and arranged in a direction of application of the seating load, the first wall surface being positioned on a side opposite to the direction of application of the seating load and the second wall surface being positioned on a side of the direction of application of the seating load; the seating sensor comprises a first flexible member opposed to the first wall surface of the sensor receiving space and a second flexible member opposed to the second wall surface; and the accidental operation preventing device is positioned between the first wall surface of the sensor receiving space and the first flexible member of the seating sensor. - View Dependent Claims (9)
