  • Patent number: 7614702
    Abstract: A rear seat system of a motor vehicle includes at least one seat that has a backrest and a seat surface. The backrest has, laterally, a backrest sidewall extending at least over part of the height of the backrest, and can be folded over forward about a pivot axis independently of the lateral backrest sidewall or cheek. It is important that the backrest sidewall is mounted such that it can be adjusted by pivoting about the pivot axis and is configured in such a manner that it can be adjusted together with the backrest into at least two different backrest inclination positions. In this case, the backrest can be folded over forward about the pivot axis from each backrest inclination position independently of the lateral backrest sidewall.
