US Patent 11097753 Modular personal protection device under the vehicle

An airbag module and a rail vehicle with an airbag module are described herein. The airbag module includes a support flap, which is pivotably mounted on its rear end, such that the airbag module is convertable from a closed state into an open state by pivoting the support flap. The airbag module further includes an airbag, which is folded in the closed state of the airbag module and unfolded in the open state of the airbag module, so that the unfolded airbag and the support flap together form an impact protection for a person on the track. Furthermore, a rail vehicle with one or a plurality of airbag modules is described.
