CRUSHING SENSOR DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent a weight and a cost of a crushing sensing device from being substantially increased and perform a sensing of a side crushing state of wide range from a door and a center pillar within a short period of time by one acceleration sensor. SOLUTION: An acceleration sensor 18 is arranged at an upper part of a locker 16 ranging from a central part in a forward or rearward direction of a front side door 12 to a center pillar behind the door. The acceleration sensor 18 is fixed to a locker 16 through a bracket 24. A lower part of the front side door 12 is oppositely faced with a clearance 28 being opened at a location opposite against the acceleration sensor 18 in which the bracket 24 is held in it. A torque box 38 is arranged on a bottom side 34B of the door inner panel 34 with a clearance 36 being opened between itself and a door outer panel 32. The acceleration sensor 18 can be relatively displaced into a compartment together with the bracket 24 in respect to the locker 22.
