Abstract: An electric seat in which other members are prevented from being damaged and thus safety is ensured. When a current consumed by the leg rest motor during the downward pivotal movement of the leg rest is larger than the reference value for the downward movement of the leg rest, the switch for the motor is opened. In a case where the leg rest is pivoted downward with a baggage placed in the operating space of the leg rest in the bed position, when the leg rest abuts against the baggage, a large load is applied to the leg rest and a current that exceeds the reference value for the downward movement of the leg rest flows in the leg rest motor, the switch is opened, the respective motors are actuated, and the downward pivotal movement of the leg rest is stopped. Therefore, the leg rest is prevented from pressing the baggage unnecessarily, thereby preventing the baggage from being damaged.

Abstract: In a mounting structure, a seat occupant sensor is disposed on the central region of the bearing surface of the foam of a seat, and signal lines that connect the sensor to an ECU cross a groove formed on foam. Deeper portions are formed on the bottom of the groove so as to correspond to the portions of the groove where the signal lines cross the groove. Further the portions of a wire buried in the foam corresponding to the deeper portions are routed so that the wire bypasses the deeper portion. According to this arrangement, the signal lines can move freely in the deeper portion of the groove, and therefore the signal lines are immune to breaking even if the foam deforms. Thus the reliability and the durability of the seat occupant sensor are ensured.
