Vehicle seat, in particular motor vehicle seat

摘要

A vehicle seat, in particular to a motor vehicle seat, having a base structure (3) that is to be connected to the vehicle structure (S) and a backrest (10) that can be moved relative to the base structure (3) by kinematics, such as to transfer the vehicle seat (1) from at least one usage position allowing a person to sit down to a non-usage position or to another usage position. A multi-bar linkage, in particular a four-bar linkage (V), exists at least temporarily, which linkage controls the kinematics. A leaf spring (30) is provided in the vehicle seat. The leaf spring forms a gear element of the multi-bar linkage in the relaxed extended state thereof.

主权项

1. A vehicle seat for a vehicle with a vehicle structure, the vehicle seat comprising:
a base structure which is connected to the vehicle structure; a fitting; and a backrest which can be moved relative to the base structure, the backrest including an arm and being connected to the base structure via the fitting, the backrest and base structure defining a kinematic system including an at least temporarily active multi-bar mechanism comprising a four-bar mechanism, wherein the vehicle seat can be moved from at least one position for use in which it is possible to be seated, into a non-use position or into another position for use, wherein the four-bar mechanism controls the kinematic system, wherein a leaf spring is provided which forms, in a relaxed extended position thereof, a member of the multi-bar mechanism, and in a bent position, the leaf spring is adapted to build up tension in order to counteract a gravitational force of the backrest, the leaf spring being fitted to the base structure offset with respect to the fitting and to the arm of the backrest structure in a manner offset with respect to a backrest articulation.
