A knee airbag apparatus includes an airbag that is configured to be accommodated in a holder arranged in an instrument panel of a vehicle. The airbag includes an upper inflation portion and a lower inflation portion. The upper inflation portion is configured to be deployed and inflated from the holder along a rear surface of the instrument panel in a rear upward direction to protect a knee of a lea of the occupant. The lower inflation portion is configured to be deployed and inflated from the holder in a downward direction or a diagonally rear downward direction such that a lower end of the lower inflation portion reaches a position where the lower end contacts an instep of a foot of the leg of the occupant or a position lower than the instep to protect the foot of the occupant.

A seat includes a seatback. The seat includes a seat bottom extending away from the seatback in a seat-forward direction to a front of the seat bottom distal to the seatback. The seat bottom has a top surface defining an occupant-leg area. The seat includes an airbag supported by the seat bottom at the front of the seat bottom and inflatable from an uninflated position to an inflated position. The airbag in the inflated position extends away from the seat bottom in the seat-forward direction and includes an uppermost surface positioned below the occupant-leg area of the seat bottom.

An occupant protecting device for a vehicle has a knee airbag that is disposed at a seat front side of a vehicle seat, and that, at a time of a front collision of a vehicle, deploys, and restrains leg portions of a vehicle occupant seated in the vehicle seat. A foot airbag is disposed at the seat front side of the vehicle seat. At a time of a front collision of the vehicle, when a seat front-rear direction position of the vehicle seat is disposed further toward a rear side than a predetermined position, the foot airbag deploys between the knee airbag and the leg portions of the vehicle occupant seated in the vehicle seat, and restrains the leg portions of the vehicle occupant seated in the vehicle seat.

A vehicle includes a front bulkhead. The vehicle includes an airbag inflatable from an uninflated position to an inflated position adjacent the bulkhead. The vehicle includes a track fixed relative to the bulkhead. The vehicle includes a slider fixed to the airbag and slidable along the track between a first position when the airbag is in the uninflated position and a second position when the airbag is in the inflated position.

An amusement device seat assembly includes a seat to allow a passenger to sit. A leg space is provided under a seat base for holding a left and right leg of the passenger. The seat assembly includes a leg locking device for retaining an in the leg space introduced lower leg of the passenger. The leg locking device includes a central mount for preventing a laterally inwardly directed movement of a leg. A lateral mount prevents a forwardly directed movement of the lower leg. A bracket which may be operatable by the passenger himself is movable to provide an open or closed configuration of the leg locking device. In the closed configuration, an outer bracket extension prevents a laterally outwardly directed movement of a leg of a passenger. Advantageously, an intuitively working leg locking device is provided which contributes to a high level of operational reliability.

The invention describes a vehicle occupant restraint system (2) comprising a control unit and at least two restraint elements (8, 10) for the protection of lower extremities (6, 6′, 7, 7′) in the area of a footwell (4) of a vehicle of a vehicle occupant seated in a particular vehicle seat of the vehicle, wherein a first restraint element (8) is configured as a knee airbag module (12), wherein a second restraint element (10) is provided for mounting into the footwell (4) of the vehicle, especially in an area of the footwell (4) of the vehicle arranged in the vehicle longitudinal direction (x) ahead of the knee airbag module (12), wherein, in a situation of restraint, the control unit can differentiate between different situations, wherein the control unit, in the situation of restraint, activates at least the first restraint element (8) and, depending on the given situation, additionally activates the second restraint element (10) and/or a partial element of the first restraint element (8) and/or a partial element of the second restraint element (10).

A restraint system for helping to protect an occupant of a vehicle having a roof and a cabin with a seat for the occupant includes an airbag having a stored condition within a base of the vehicle seat and being inflatable to deploy upwards in the cabin and between legs of the occupant to a deployed condition in front of the occupant. The airbag including a lower end having a pair of projections spaced apart in a forward-rearward direction of the vehicle. The airbag being configured to utilize the vehicle seat as a reaction surface for restraining the movement of the airbag in response to occupant penetration into the airbag.

A vehicular seat cushion airbag is disclosed. The seat cushion airbag includes a first cushion, which is mounted on a seat cushion of a vehicle so as to be expanded at the rear portion of a passenger's thigh, and a second cushion, which extends from the first cushion in an upward direction of a bolster portion of the seat cushion so as to be expanded toward the lateral side surface of the passenger's thigh, wherein the first cushion is expanded at the rear portion of the passenger's thigh so as to prevent forward movement of the passenger's pelvis, and the second cushion is expanded toward the lateral side surface of the passenger's thigh so as to prevent outward spreading of the passenger's legs.
