Crash-arresting unit, in particular for a vehicle seat, and vehicle seat
A crash-arresting unit for a vehicle seat may have a locking element and an actuating unit. The locking element can be brought into form-fitting engagement with a mating element via the actuating unit. The actuating unit may be an electromechanical actuating unit having a fusible wire, where destruction of the fusible wire frees a movement of the locking element in the direction of the mating element.
1. A crash-arresting unit for a vehicle seat, comprising:
a locking element and an actuating unit, wherein the locking element can be brought into form-fitting engagement with a mating element via the actuating unit,
wherein the actuating unit is an electromechanical actuating unit having a fusible wire, wherein destruction of the fusible wire pushes the locking element in the direction of the mating element.
2. The crash-arresting unit as claimed in claim 1 , wherein the locking element is a pawl.
3. The crash-arresting unit as claimed in claim 1 , wherein the mating element is a toothed segment.
4. The crash-arresting unit as claimed in claim 1 , wherein the fusible wire can be destroyed by a current surge.
5. The crash-arresting unit as claimed in claim 1 , wherein a spring in a preloaded state is held in the preloaded position by the fusible wire.
6. The crash-arresting unit as claimed in claim 5 , wherein the spring is a compression spring.
7. The crash-arresting unit as claimed in claim 6 , wherein the fusible wire and the spring are constituent parts of the electromechanical actuating unit.
8. The crash-arresting unit as claimed in claim 5 , wherein the spring actuates an actuating rod, and the actuating rod acts on the locking element in such a way that the locking element comes into engagement with the mating element as soon as the fusible wire is destroyed.
9. The crash-arresting unit as claimed in claim 5 , wherein the spring actuates an actuating cable as soon as the fusible wire is destroyed, and in that the actuating cable acts on the locking element in such a way that the locking element comes into engagement with the mating element.
10. The crash-arresting unit as claimed in claim 5 , wherein the spring directly pivots the locking element in such a way that the locking element comes into engagement with the mating element as soon as the fusible wire is destroyed.
