Abstract

A vehicle seat having a seat part, a backrest, a kinematics system for transferring the vehicle seat from a use position into an entry position and back, a drive apparatus for driving the kinematics system, and a coupling apparatus for coupling the drive apparatus to the kinematics system. The coupling apparatus has a pawl and a counter-element. The pawl and the counter-element are locked to one another in order to couple the drive apparatus to the kinematics system, wherein the pawl is released from the counter-element by an actuation of the coupling apparatus, resulting in the drive apparatus being decoupled from the kinematics system. The pawl is configured as a bracing pawl, and the pawl and the counter-element are locked to one another beyond a self-locking action.

Dependent claims

A vehicle seat, comprising:

a) a seat part,
b) a backrest,
c) a kinematics system for transferring the vehicle seat from a use position, suitable for passenger transport, into an entry position and back,
d) a drive apparatus for driving the kinematics system, wherein the drive apparatus selectively rotates both a coupling link, that is driven by a spindle nut, and a pawl, and
e) a coupling apparatus for coupling the drive apparatus to the kinematics system, the coupling apparatus having the pawl and a counter-element comprising a pin,
it being possible for the pawl and the counter-element to be locked to one another in order to couple the drive apparatus to the kinematics system, and it being possible for the pawl to be released from the counter-element by an actuation of the coupling apparatus, as a result of which the drive apparatus can be decoupled from the kinematics system,
wherein the pawl is configured as a bracing pawl, it being possible for the pawl and the counter-element to be locked to one another beyond the self-locking action.
