Further, the path through which the wiring member passes can be shortened, that is, the wiring member can be shortened.

For these reasons, the wiring member does not deteriorate the sitting comfort when the occupant sits on the seat cushion.

In addition, since the wiring member is guided by the pad protrusion and the pad trough by passing through the gap between the pad protrusions and the gap between the pad troughs, a special fixing member is not required and the workability is improved. It is possible to contribute to cost reduction.

Further, the acoustic vibration transmitted from the acoustic vibrator to the wiring member is absorbed by the pad rest portion. Explaining this point further, the pad reed portion has not only a guide function for guiding the wiring member to be inserted and arranged in a predetermined path together with the pad convex portion, but also the wiring member is inserted and arranged in a gap communicating with the vehicle width direction. By doing so, the wiring member and the pad reed portion are brought into contact with each other only in this gap section to secure a contact range, and the vibration absorption function of reliably absorbing the acoustic vibration transmitted from the acoustic vibrator to the wiring member in this contact range. Is. Therefore, it is possible to prevent the wiring member from resonating with acoustic vibration and generating abnormal noise. Further, it is possible to prevent the wiring member from being displaced due to resonance with the acoustic vibration and coming into contact with, for example, the frame or the seat spring of the seat back and causing abnormal noise.

In the present invention as set forth in claim 2 of the utility model registration, the wiring member is provided on the back surface of the seat cushion with a certain distance from the seat track and the lock plate for seat slide fixed to the frame of the seat cushion. Since there is a portion fixed to the seat cushion so as to be substantially parallel, even if the seat is slid, the wiring member does not mesh with the lock plate or the like. Therefore, there is no possibility of damaging the wiring member.
