Seat-integrated side-impact protection device and seat-integrated head-side airbag module

The airbag (14) is integrated into an upper corner (10) of the seat backrest (2). In this region there is also a seat belt resting surface (18) for the shoulder region of the belt (6). Between the two, there is a belt guide (24), which prevents the belt from being displaced over the exit opening (32, 34) for the airbag. The rest and guide may themselves be integrated into a single module.
