[0070] Figure 1 to Figure 4 Various views of one embodiment of the seat frame 11 of the car seat according to the invention are shown in normal positions, which appear when the back or upper body of the car seat user is not turned. The seat frame 11 is basically composed of a seating surface frame 12 and a back frame 13 pivotally and obliquely provided thereon. In the present embodiment, the back frame 13 is arranged to be pivotable about the axis 21 on corner brackets 29 which are fixedly arranged and fixed to the seating surface frame 12 .

[0071] The back frame 13 basically consists of central, left and right back longitudinal links 14 , 15 and 16 interconnected by lower and upper cross braces 17 and 18 .

[0072] The lower cross strut 17 is essentially formed by a central region 22 and regions 23 and 24 arranged thereon and forming an angle with respect to the longitudinal direction 20 of the vehicle. The angle 25 formed by the aforementioned regions 23 and 24 with the...

technical field [0001] The invention relates to a vehicle seat according to the preceding claim 1 . Background technique [0002] Seats of this type are currently known in many different configurations. The seat frame and the backrest frame of the seat frame may differ in their upholstery. These known seats are adjustable in terms of seat profile and backrest profile, but generally do not adequately fit the user's ergonomics, meaning that comfort is thus limited and the user's back does not pass through the backrest frame Get adequate support in every position, which often leads to back discomfort. [0003] For example, a motor vehicle seat is known from DE 4405397C1, the backrest frame of which is subdivided into a plurality of subsections which are mutually pivotable about a vertical axis of rotation. [0004] A car seat equipped with a backrest frame movable in this way does improve the user's access to the trigger member behind the seat and, in coupes, even the rear s...
