An adjustment mechanism for a headrest for a seat has a scissor lever. The adjustment mechanism has at least one first lever arm and at least one second lever arm. A compensating lever arm is arranged at at least one lever arm end of each lever arm. A free end of each compensating lever arm has an attachment structure for attaching the compensating lever arm to a body. A lever arm end opposite the compensating lever arm of each lever arm has an attachment structure for attaching the lever arm to a body. A headrest for a vehicle seat, which has a headrest body is also provided.

Adjustment mechanism and headrest

A system with a pivotable armrest () and a locking aid (), wherein the armrest () is coupled to a holding device () so as to be pivotable about a primary axis () and is reversibly transferable between a use position and a stowage position via a transition position. The armrest () is connected to a connecting element () for rotation therewith. The locking aid () is arranged on the connecting element (). The locking aid () is in frictional contact with the holding device () at a contact point or along a contact surface. The locking aid () is configured in such a manner that the frictional contact between holding device () and locking aid () is greater in a transition position than in the use position and/or in the stowage position.

System with a pivotable armrest and a locking aid

A system includes a pivotable armrest () and a pendulum element (). The armrest () is pivotably hinged on a holding device () around a primary axis (). The armrest () is connected rotatably fixed to a connection element (). The holding device () includes the pendulum element (). The pendulum element () is pivotable around a secondary axis (). The connection element () and the pendulum element () are configured such that the pendulum element () is pivoted into a first position when a force is exerted on the system. The pendulum element () pivoted in the first position interlockingly interacts with the connection element () in such a way that a pivoting of the connection element along a second direction of rotation () is countered. The first direction of rotation () runs counter to the second direction of rotation ().

System comprising a pivotable armrest and a pendulum element

A locking device for a headrest has a headrest rod, a guide sleeve for the headrest rod and a blocking element. The blocking element is displaceable relative to the guide sleeve between a locking position, in which the blocking element is in engagement with a recess in the headrest rod, and a unlocking position, in which the blocking element is not in engagement with recesses in the headrest rod. The blocking element is pivotable in relation to the guide sleeve about an axis of rotation parallel to the headrest rod. The blocking element is mounted in the guide sleeve such that, when there is a relative rotational movement between the guide sleeve and the headrest rod, the blocking element rotates at least partially jointly in conjunction with the headrest rod about the axis of rotation.

Locking device for a headrest

In a vehicle seat comprising a head restraint and a seat back, the head restraint can be moved between a usage position and a non-usage position. According to the invention, at least one interfering element is pivotably mounted inside the seat back by means of a pivoting device, wherein in the non-usage position the head restraint positions the at least one interfering element of the seat back in such a way that the interfering element forms at least one contact point with the torso of a vehicle occupant located on the vehicle seat.

Vehicle seat comprising a head restraint

A vehicle head restraint on a seat back is adjustable in height from a non-usage position to a usage position. The head restraint is disposed on a retaining element formed from a U-shaped tubular section and of which a horizontally disposed section forms the axis of rotation of the head restraint. The head restraint and retaining element are coupled by means of a spring element such that a biasing force of the spring element is applied to the head rest, wherein sections of the spring element engage in respective cutouts disposed on both sides in the region of rounded portions of the retaining element, and the biasing force generated rotates a lower end of the head rest automatically in the direction of the retaining element as the head rest is moved from the non-usage position to the usage position.
