Vehicle seat and method for stowing a seat element
View Patent ↗The invention relates to a vehicle seat ( 1 ) comprising a seat element ( 2 ) that can be vertically adjusted from an operational position to a stowed position. Said vehicle seat has ⋅—a first locking element for securing the seat element in the operational position, and ⋅—a positioning means for positioning the seat element in a transitional position, the seat element being manually transferable directly or indirectly from the transitional position to the stowed position.
1. A vehicle seat having a seat element which is vertically adjustable from a use position into a storage position, wherein the vehicle seat has:
a first locking element for securing the seat element in the use position,
a positioning means for positioning the seat element in a transition position,
an articulation system consisting of a first link and a second link for folding up the seat element, and
a further articulation system consisting of a third link and a fourth link for transferring the seat element from the transition position into a storage position,
wherein the seat element is transferable manually directly or indirectly from the transition position into the storage position,
wherein the positioning means comprises a spring element,
wherein a restoring force of the spring element keeps the seat element in the transition position,
wherein the articulation system is a four-bar linkage,
wherein the further articulation system is a four-bar linkage,
wherein the spring element is integrated in the articulation system, and
wherein the spring element is operatively connected to the third link.
2. The vehicle seat as claimed in claim 1 , wherein the vehicle seat has a backrest element, wherein the backrest element is pivotable about a primary axis relative to the seat element.
3. The vehicle seat as claimed in claim 2 , wherein the first locking element is unlockable by pivoting the backrest element and/or actuating an actuating means.
4. The vehicle seat as claimed in claim 2 , wherein the backrest element is transferable into a stowage position by pivoting, wherein, in the stowage position, the backrest element is arranged in a substantially form-fitting manner along a vertical adjustment direction running substantially perpendicularly to a main plane of extent of the seat element.
5. The vehicle seat as claimed in claim 1 , wherein the vehicle seat has a second locking element for securing the seat element in the storage position.
6. The vehicle seat as claimed in claim 5 , wherein the vehicle seat has a third locking element for securing the transition position.
7. A method for stowing a vehicle seat, wherein:
in a first method step, a first locking element for securing a seat element of the vehicle seat in a use position is released,
in a second method step, the seat element is kept in a transition position, and
in a third method step, the seat element is transferred from the transition position into the storage position,
wherein the vehicle seat includes:
an articulation system consisting of a first link and a second link for folding up the seat element, the articulation system being a four-bar linkage,
a further articulation system consisting of a third link and a fourth link for transferring the seat element from the transition position into a storage position, the further articulation system being a four-bar linkage,
wherein a spring element is integrated into the articulation system, and
wherein the spring element is operatively connected to the third link.
8. The method as claimed in claim 7 , wherein a backrest element which is pivotable about a primary axis relative to the seat element:
is transferred in the first method step and is used as a flow of force means for transferring the seat element into the storage position, or
is transferred after the third method step into a stowage position.
