PROBLEM TO BE SOLVED: To provide an occupant seating sensor installing structure capable of ensuring the reliability and durability of the sensor without impairing the design of a seat. SOLUTION: In this occupant sensor, a signal line 5 connecting sensors arranged in the seat surface center part of a form 3 and an ECU is arranged so as to intersect a hang groove 7 of the form 3. A deep groove portion 12 is provided by deeply forming the bottom surface of the hang groove 7 intersecting the signal line 5, and a wire 8 buried in the form 3 is removed from the deep grove potion 12. The folded portion of the signal line 5 is arranged in the deep groove portion 12 in such a way as to have flexibility. Therefore, the movement of the signal line 5 is not restricted in the deep groove portion 12, and flexibility can be added on the movement. Consequently, large stress is not applied to the folded portion of the signal line 5 even if the form 3 is deformed, a break of the signal line 5 is prevented, and the reliability and the durability of the occupant seating sensor can be ensured. |
