Autoliv has been granted a patent for a device that allows for the removable mounting of an airbag module on a steering wheel. The device includes hooks and insertion elements that cooperate with a resilient ring to securely hold the airbag module in place. The resilient ring can rotate and has a locking portion that is blocked by a stop on the steering wheel, preventing movement in a specific direction.

Removable mounting device for airbag module on steering wheel
A recently granted patent (Publication Number: US11772591B2) describes a device for removably mounting an airbag module to a steering wheel. The device includes at least one hook connected to either the airbag module or the steering wheel, which cooperates with at least one insertion element located on the other component. A resilient ring is used to form a holding element for the hook, with a mounting portion of the ring allowing for rotation relative to the airbag module or steering wheel. The resilient ring also features a locking portion, which is blocked by a first stop on the airbag module or steering wheel to prevent movement in a perpendicular direction to the mounting rotation axis.
In addition to the above, the patent also mentions several other features of the device. The first stop, which blocks the movement of the locking portion, is positioned opposite the zone of interaction on the side opposite the hook. The retaining portion of the resilient ring may be comprised or merged into the mounting portion. Furthermore, the airbag module or steering wheel may include a second stop to block movement in a second perpendicular direction, as well as a third stop to block movement in a third perpendicular direction parallel to the mounting rotation axis. The first stop may be positioned between the second and third stops. Additionally, a guide element may be included to facilitate the rotation of the resilient ring. The resilient ring forms an open loop surrounding the hook, and a fourth stop may be present to block movement in a second perpendicular direction and also serve as a guide element for dismantling the ring using a tool.
Overall, this patent describes a device that allows for the secure and removable mounting of an airbag module to a steering wheel. The use of a resilient ring and various stops and guide elements ensures proper alignment and stability of the airbag module during operation.
