Claims (7)

[Claims] 1. A collision detection mechanism, which comprises a moving member that moves due to the impact of a vehicle collision, detects a vehicle collision, one end of which is linked to one end of the moving member, and the other end of which is a door. A spring member which is linked to the lock and generates a biasing force for releasing the locked state of the door lock,
When a collision of a vehicle is detected by the collision detection mechanism and the movable member is moved to release the locked state of one end of the spring member, the door lock release mechanism releases the locked state of the door lock by its urging force. A door unlocking device comprising: 2. The door unlocking device according to claim 1, wherein the moving member of the collision detection mechanism is a swing member that swings about one point as a fulcrum. 3. The door unlocking device according to claim 2, wherein the swing member includes a weight that acts as an inertial mass at the time of a vehicle collision. 4. The spring member according to claim 3, wherein one end of the spring member is locked to the door and the other end is locked to a link connecting the bell crank and the door lock knob, and is swingably supported by the door. When the swing member of the collision detection mechanism swings due to inertia of the weight when the swing member collides, the engagement state of the engagement end of the spring member with the swing member is released, thereby attaching the spring member. A door lock releasing device having a structure capable of releasing a locked state of a door lock via the link by a force. 5. The collision detection mechanism according to claim 3, wherein the spring member is coaxially disposed with a bell crank connected to a link that communicates with the door lock, and swings in a selectively interlocking manner. A first swinging member that is locked to the swinging member and has the other end linked to a bell crank, and one end that is locked to the door and the other end that is locked to the first swinging member. A first spring, and the one end of the second rocking member by rocking due to inertia of the weight at the time of collision of the rocking member of the collision detection mechanism that is rockably supported by the door. The lock state of the door lock can be released via the link by swinging the first swing member and the bell crank by the urging force of the first spring. Door lock solution characterized by being composed of Apparatus. 6. The spring member according to claim 3, wherein the spring member is swingably supported by the door, one end of which is locked to the swing member of the collision detection mechanism, and the other end of which is linked to a bell crank. 2 rocking member, and a second one end of which is locked to the door and the other end of which is locked to the second rocking member.
Of the second swinging member by swinging due to inertia of the weight at the time of a collision of the swinging member of the collision detection mechanism that is swingably supported by the door. By releasing the stop state, the biasing force of the second spring can swing the second swing member and the bell crank to release the locked state of the door lock via the link. Door lock release device. 7. The swing member according to claim 3, wherein the spring member swings around a fulcrum of a lock lever of the door lock that communicates with a link that connects to a bell crank, and one end of the swing member of the collision detection mechanism. A third swing member locked to the lock lever and the other end linked to the lock lever; and a second spring having one end locked to the door and the other end locked to the third swing member. Locking the one end of the third rocking member by rocking due to inertia of the weight when the rocking member of the collision detection mechanism rockably supported by the door lock main body collides. When the state is released, the third swing member is swung by the urging force of the third spring, and the locked state of the door lock is released via the lock lever. Door unlock device.
