Abstract: A connection arrangement, that connects a first component (2) to a second component (3), includes a screw (1) with a screw head (10) and a threaded shaft (11) which has an exterior thread (12). The first component includes a mating connection piece (20), which has a support surface (21) and a collar (23). A depression (22) encircles the collar (23) and is formed in the support surface (21). A protrusion (14) is arranged on a screw head lower face (13), facing the collar (23). The protrusion is operatively connected to the depression (22) in the support surface (21) of the mating connection piece (20) in an assembled state of the screw (1), with the interposition of the second component. A vehicle seat (100) includes the first component and the second component, fixed by the connection arrangement. A methods for producing the connection arrangement and for connecting the components are provided.

Abstract: A vehicle seat (1), in particular a motor vehicle seat, has a seat part (4), a backrest (2) which has a backrest structure (20) as a supporting structure, and at least one fitting (6). The fitting (6) connects the backrest structure (20), at least indirectly, to the seat part (4) and is pivotble relative to the seat part (4). A backrest adapter (12) connects the backrest structure (20) to a fitting part of the at least one fitting (6); wherein the backrest structure (20) has a receiving space (22) in which the backrest adapter (12) is accommodated in a form-fitting manner at least in sections.
