Patent ID: 11945346
Assignee: FAURECIA AUTOSITZE GMBH
Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 9:
10. A vehicle seat crash securing device comprising
a) a seat frame part,
b) an actuator fixed to the seat frame part,
c) a support structure supporting the seat frame part and configured for allowing an adjustment of a height of the seat frame part,
d) a locking device configured for locking a height of the seat frame part, the locking device comprising a locking element and a counter-locking element, the locking element being movable between
a locked position wherein the support structure is locked by an engagement of the locking element and the counter-locking element so that the height of the seat frame part is fixed and secured and
an unlocked position wherein the locking element and the counter-locking element do not engage each other so that the height of the seat frame part can be adjusted,

e) a belt rope which is connected in a first end region to the actuator and in a second end region to a seat belt buckle, the belt rope comprising an intermediate region which is located between the first end region and the second end region wherein the intermediate region is pressed with a contact force against a follower which allows the generation of a friction force between the belt rope and the follower,
f) a blocking element supported by the seat frame part, the blocking element being movable between a blocking position and a releasing position wherein the blocking element
fa) in the blocking position blocks and holds the locking element of the locking device in the unlocked position and
fb) in the releasing position releases the locking element so that it can be moved from the unlocked position into the locked position,

g) a spring element which biases the locking element towards the locked position and in the releasing position of the blocking element moves the locking element from the unlocked position into the locked position,
h) wherein the actuator
ha) is actuated in the case of a crash
hb) tightens the belt rope by the application of a pulling force on the first end region and

i) the blocking element is configured to be moved by the friction force imparted by the belt rope on the blocking element to move the blocking element from the blocking position into the releasing position, the friction force being induced by the actuator.
