On-vehicle component fixation-release apparatus
First Claim
1. An on-vehicle component fixation-release apparatus that releases fixation of on-vehicle components attached to a vehicle body by a fastening member, said on-vehicle component fixation-release apparatus comprising:
- a dismantling means that enables dismantling of the fastening member or a fastening portion at which the fastening member is mounted, anda determination means that determines whether the dismantling by the dismantling means is allowed in accordance with an input signal that is input from outside the vehicle,wherein;
the fastening member or the fastening portion is formed by at least two detachably fixed members that are formed with materials having mutually different expansion coefficients;
with a convex insertion portion formed on a member with a relatively small expansion coefficient, and a concave engaging portion that has a predetermined interference with respect to the insertion portion formed on a member with a relatively large expansion coefficient; and
the insertion portion fixed to the engagement portion in a state of being inserted therein and interference fitted, andthe on-vehicle component fixation-release apparatus further comprising a heating means that, in accordance with a determination result of the determination means, heats the member until fixation between the insertion portion and the engagement portion is released.

Abstract
To readily remove on-vehicle components from a vehicle body, suitably reflecting the state of the vehicle or occupant in addition to the will of the operator.
The safety confirmation device 11 determines whether or not to permit actuation of the separation actuator 13, that is, whether to set the switch 12 to the ON state to allow an electrical connection from the power supply 14 to the separation actuator 13, based on the signals input from the external input receiving portion 21, the occupant protection device 22, the status quantity sensor 23, and the input portion 24, and outputs a gate signal corresponding to this determination result to the switch 12. Electrification of the separation actuator 13 from the power supply 14 via the switch 12 releases the fixation of an on-vehicle component by disassembling the fixation member that fixes the on-vehicle component to the vehicle body.
