Motor vehicle seat featuring coupling between the backrest movement and the seat part movement, and motor vehicle comprising such a motor vehicle seat

A motor vehicle seat (2) comprising a seat part (6), which may be moved by means of a seat part mechanism (20) from an operating position into a non-operating position, a locking means (34) being provided for the releasable locking of the seat part (6) in the operating position, a backrest (4), which may be swiveled by means of a backrest mechanism about a swivel pin (10) in the direction of the seat part (6), and a coupling element for coupling the movement of the backrest (4) to the movement of the seat part (6), the seat part (6) being locked in the operating position during a first swiveling movement of the backrest (4) in the direction of the seat part (6), the coupling element in a more extensive second swiveling movement of the backrest (4) in the direction of the seat part (6) cooperating with the locking means (34), such that the locking of the seat part (6) is triggered and the seat part (6) may be moved during an even more extensive third swiveling movement of the backrest (4) in the direction of the seat part (6) by the coupling element from the operating position into the non-operating position, characterized in that:

• the coupling element cooperates with the backrest mechanism and the seat part mechanism (20) such that the coupling element exerts a tensile force on the seat part mechanism (20), in order to move the seat part (6) from the operating position into the non-operating position,
• the coupling element cooperates with the backrest mechanism and the locking means (34) such that the coupling element exerts a tensile force on the locking means (34) in order to trigger the locking of the seat part,
• a projection is provided on the coupling element which may be pulled against the locking means (34) such that the locking of the seat part (6) is triggered,
• the seat part (6) is pretensioned into the operating position, such that it may be moved counter to the pretensioning into the non-operating position and when the backrest (4) is swiveled back automatically returns into the operating position,
• the seat part mechanism (20) comprises a spring element (38) for pretensioning the seat part (6) into the operating position,
• the locking means (34) cooperate with the seat part mechanism (20) such that the locking means (34) automatically lock the seat part (6) in the operating position when the seat part (6) is moved from the non-operating position again into the operating position,
• the coupling element is secured at a first contact point (18) to the backrest mechanism and at a second contact point (30) to the seat part mechanism (20), the distance between the first and second contact point (18;
• 30) during the first swiveling movement being able to be altered, preferably also during the second swiveling movement, and
• the coupling element comprises a first strut (46) which is secured in an articulated manner at the first contact point (18) to the backrest mechanism, and a second strut (48) which is secured in an articulated manner at the second contact point (30) to the seat part mechanism (20), the first and the second struts (46;
• 48) being connected to one another via a simple pivot (50).
