Embodiment Construction

[0070] Hereinafter, the present invention will be exemplified by embodiments. It should be appreciated, however, that the embodiments are included to explain the principles of the invention, rather than to limit the scope of the invention, which is defined by the appended claims. Features from one embodiment may be combined with one or more features from any other embodiment.

[0071] will refer to Figure 1 to Figure 5 The present invention and its advantages over the prior art are further explained. Orientation as used herein refers to known extensions and orientations on and in the vehicle. In this way, the vehicle extends in the longitudinal direction X, the lateral direction and the height direction Z, these directions being perpendicular to each other, see Figure 1a . The longitudinal direction X is the normal driving direction of the vehicle. The lateral direction is the lateral direction of the vehicle and is therefore not shown.

Abstract

The invention relates to a knee airbag device (4) for a vehicle (2). The knee airbag arrangement includes an inflatable airbag (6) and an external tether (7). The airbag is adapted to be inflated to a location between the vehicle's instrument panel (8) and the knee / shin region (14) of the vehicle occupant (16). The knee airbag is adapted to form a first deployment mode or a second deployment mode in a deployed state. The external tether controls the deployment of the airbag to the second deployment mode. The depth of the airbag in the second deployment mode (D 2 ) is greater than the depth of the knee airbag in the first deployment mode (D 1 ). The depth of the airbag in the deployed state is the maximum extent of the airbag perpendicular to the dashboard in the knee / shin region. The invention also relates to a vehicle comprising the knee airbag device and a method for deploying an airbag of the knee airbag device.

Description

technical field [0001] The present invention relates to a knee airbag device for a vehicle. The invention also relates to a vehicle comprising the knee airbag device. The invention also relates to a method for deploying an airbag of the knee airbag arrangement. Background technique [0002] The vehicle may be equipped with knee airbags for protecting the knee / shin region of the vehicle occupant during a collision. The knee airbag is intended to restrain the knee / shin region of the vehicle occupant in its inflated position, thereby protecting the vehicle occupant from collision with interior objects such as the dashboard in front of the seat. Various knee airbags are known for providing protection to vehicle occupants of different sizes and different crash modes. [0003] With the introduction of vehicles with AD capabilities, ie autonomous driving capabilities, it is possible for occupants to move and adjust vehicle seats more freely than is possible today. In particular...
