First Claim
Patent Images
1. A load detection sensor unit which is disposed below a sheet cushion, comprising:
- a load detection sensor which includes a pair of electrodes facing each other with a predetermined gap interposed therebetween and a metal plate covering at least a part of one electrode located near the sheet cushion among the pair of electrodes from the sheet cushion;
a pressing member that includes a pressing portion pressed against the sheet cushion and harder than the sheet cushion; and
a first movement regulation member that regulates a relative movement between the pressing member and the metal plate in a plane direction of the metal plate,wherein the pair of electrodes contacts each other when the metal plate is bent in a case in which the pressing portion presses a part of the metal plate.

12. A load detection sensor unit which is disposed below a sheet cushion, comprising:
-
a load detection sensor which includes a pair of electrodes facing each other with a predetermined gap interposed therebetween and a metal plate covering at least a part of one electrode located near the sheet cushion among the pair of electrodes from the sheet cushion; a pressing member that includes a pressing portion pressed against the sheet cushion and harder than the sheet cushion, wherein the pair of electrodes contacts each other when the metal plate is bent in a case in which the pressing portion presses a part of the metal plate, wherein the load detection sensor further includes a sheet-shaped spacer having an opening formed therein and a pair of insulation sheets formed on both surfaces of the spacer, wherein the pair of electrodes is provided on a surface near the spacer in the insulation sheets respectively and faces each other with the opening interposed therebetween, and wherein the metal plate is provided at the opposite side to the spacer of one of the insulation sheets, and wherein the pair of insulation sheets and the metal plate do not adhere to each other.
