Seat system for a vehicle
A seat system ( 1 ) for a vehicle, includes a plurality of seats ( 2.1 to 2.3 ) which are disposed next to one another and at least two of which are pivotable about a common pivot axis (S). At least one of the seats ( 2.2 ) that are pivotable about the common pivot axis (S) is designed in such a way that when the seat is unlocked and the backrest thereof is pivoted by more than a predefined angle of inclination, the adjacent other seat ( 2.1 ) is blocked in the unlocked state or at least the folding movement of the backrest thereof is dampened or prevented.
1. A seat system for a vehicle, the system comprising:
a plurality of seats which are arranged one beside another, each of the plurality of seats comprising a seat part and a backrest, at least two of the plurality of seats being independently pivotable about a common pivot axis, wherein at least one of the at least two seats pivotable on the common pivot axis is configured such that, in the event of an unlocking and the backrest thereof being pivoted from a normal or seating position beyond a predetermined angle of inclination into a forward position, an adjacent seat of the at least two seats pivotable on the common pivot axis is blocked in an unlocked state or a folding action of the backrest thereof is damped or blocked, wherein a spring device or a damping device or both a spring device and a damping device is arranged in a region of the common pivot axis of the at least one of the plurality of the seats which is to be pivoted.
2. The seat system as claimed in claim 1 , wherein a smaller-width seat of the at least two pivotable seats is configured such that, in the event of unlocking and the backrest thereof being pivoted beyond a predetermined angle of inclination, the other, adjacent seat, which is of greater width, is blocked in the unlocked state or at least a folding action of the backrest thereof is damped or blocked.
3. The seat system as claimed in claim 1 , wherein the adjacent seat in the non-folded state, in the event of unlocking, is spring-loaded in relation to a pivoted seat.
4. The seat system as claimed in claim 1 , wherein the spring device or the damping device or both the spring device and the damping device comprises a spring element, the spring element comprising at least one wrap spring.
5. The seat system as claimed in claim 1 , wherein the spring device or the damping device or both the spring device and the damping device comprises a spring element, the spring element comprising at least one helical torsion spring.
6. The seat system as claimed in claim 1 , wherein the spring device or the damping device or both the spring device and the damping device comprises a damping element, the damping element comprising at least one guide sleeve or friction clamp.
7. The seat system as claimed in claim 6 , wherein the guide sleeve or the friction clamp is slit.
8. The seat system as claimed in claim 6 , wherein:
the spring device or the damping device or both the spring device and the damping device comprises a spring element; and
the spring element wraps around the guide sleeve or the friction clamp.
9. The seat system as claimed in claim 1 , wherein the spring element has one spring end articulated on the backrest of the at least one of the seats which is to be pivoted and has another spring end articulated on the seat part of the at least one of the seats.
