AI Technical Summary
Technical Problem
Conventional seating systems in vehicles often lack an integrated armrest due to the space occupied by side airbags in the backrest, compromising comfort and safety, especially in reclining positions.
Method used
A seating system with an armrest integrated into the seat that houses a pivotable side airbag, allowing it to move within the armrest and deploy through multiple openings based on the armrest's position, triggered by a sensor for optimal restraint during accidents.
Benefits of technology
Enhances both comfort and safety by ensuring the armrest is always in an ideal position for arm support and providing selective airbag deployment based on the armrest's pivot position, effectively restraining occupants during accidents.

Abstract
Seating system (2) for a motor vehicle, comprising a backrest (4) which has at least one contact surface (5) for supporting the back of a vehicle occupant, at least one armrest (7) which has at least one support surface (8) for supporting an arm (9) of the vehicle occupant, and at least one retaining device (15) by means of which the armrest (7) is pivotably held at least indirectly on the backrest (4) about at least one pivot axis (16) relative to the backrest (4), at least one receiving space (19) extending within the armrest (7), and at least one airbag (20) held on a component of the armrest (7), which can be moved from a storage position (21) into at least one protective position (22) for restraining the vehicle occupant and is arranged at least in the storage position (21) in the receiving space (19) of the armrest (7), wherein the armrest (7) has at least one opening (23),through which the airbag (20) can be moved from the storage position (21) to the protective position (22), characterized in that the armrest (7) has at least one second opening (26) different from the opening (23), through which the airbag (20) can be moved from the storage position (21) to a second protective position (27) for restraining the vehicle occupant, and the seat assembly (2) has at least one sensor device (29) by means of which a pivot position (17, 18) of the armrest (7) relative to the backrest (4) can be detected, and at least one triggering device (30) by means of which the airbag (20) can be triggered to move from the storage position (21) depending on the pivot position (17, 18) detected by means of the sensor device (29), wherein , • when the sensor device (29) detects a first swivel position (17) of the armrest (7), the airbag (20) can be moved from the storage position (21) to the protective position (22) via the opening (23) by means of the triggering device (30). • when the sensor device (29) detects a second swivel position (18) of the armrest (7) that differs from the first swivel position (17), the airbag (20) can be moved from the storage position (21) to the second protective position (27) via the second opening (26) by means of the triggering device (30).
