Provided is an occupant's leg restraint device suitable for restraining the legs of an occupant when an automobile has an oblique collision or an offset barrier collision. The occupant's leg restraint device has an airbag and an inflator for supplying gas to the lower part of the airbag to inflate the airbag, and the airbag has a first panel on the occupant side and a second panel on the side opposite thereto. An upper part of the inside of the airbag is divided into small chambers by vertical separating panels that are joined to the first panel and the second panel and that extend vertically. In a state where the airbag has inflated, recessed portions having a depth of 20 to 40 mm are formed in the occupant-side surface of the airbag along the vertical separating panels.

The present disclosure relates to a leg protection device for an occupant protection system of a vehicle. The leg protection device includes an airbag module. The airbag module includes an airbag and a gas generator that inflates the airbag to a deployed state such that the airbag is disposed in the footwell and in front of a vehicle seat. The airbag includes a first chamber and a second chamber fluidically connected to the first chamber. The first chamber and the second chamber are deployed in the footwell to protect an occupant when the airbag is set in the deployed state. The first chamber is connected to the second chamber by a flexible connection region that diverts the airbag along the object in any spatial direction when the airbag encounters the object during deployment in the footwell.

An airbag includes a manifold having an outer panel and an inflation chamber defined at least in party by the outer panel. The airbag further includes a first compartment and a second compartment spaced from the first compartment connected to the outer panel and positioned external to the inflation chamber. A first one-way valve is in fluid communication with the manifold and the first compartment, and a second one-way valve is in fluid communication with the manifold and the second compartment.

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.

A vehicle safety seat system comprises: i) a vehicle seat configured to move to a substantially reclining position, the vehicle seat comprising a seat back and a seat bottom; and ii) a first support arm associated with the seat back, the first support arm including a first airbag on a lower surface of the first support arm, the first support arm holding the first airbag in a position above the thorax of a passenger reclining in the vehicle seat. The first airbag inflates in the event of a collision and provides protection between the first support arm and the thorax of the passenger.

An apparatus, system, and method for helping to protect occupants of a vehicle in the event of a collision. The apparatus comprising an inflatable tube having a first and second end connected to the floor of the vehicle and a middle portion therebetween and an inflator that is actuatable to direct inflation fluid into the inflatable tube in response to a vehicle collision. The inflatable tube is configured to inflate and deploy from the vehicle floor in response to receiving inflation fluid from the inflator. The middle portion extends from the floor and forms an arch into which the lower legs and/or feet of the occupant can move into in response to a collision and be restrained.

A vehicle occupant restraint device includes: a seat cushion on which an occupant is seated; a seat back that is provided on a seat rear side of the seat cushion so as to be pivotable in a seat front-rear direction and that supports a back of the occupant; an ottoman provided on a seat front side of the seat cushion so as to be pivotable in a seat up-down direction; and a fabric restraint member that is extended in a width direction of the ottoman to restrain a lower limb including a knee of the occupant when at least the ottoman is set in a raised position and the seat back takes a comfortable posture.

A vehicle, comprising a monitoring unit configured to monitor a surrounding environment of a vehicle body, a plurality of impact absorption units, an arithmetic unit configured to identify at least two characteristic parts of an object, in a case where the object is likely to come into contact with the vehicle body, based on a monitoring result of the monitoring unit, and configured to identify contact positions of the vehicle body to be respectively contacted with the at least two characteristic parts that have been identified, and an operation control unit configured to selectively operate the plurality of impact absorption units, based on the contact positions that have been identified.

The middle portion extends from the floor and forms an arch into which the lower legs and/or feet of the occupant can move into in response to a collision and be restrained.

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 given situations, wherein the given situation can be determined via a vehicle seat position and parameters relating to vehicle occupants, wherein, in the situation of restraint, when a situation is given in which the vehicle seat (5) is in a position shifted backwards, especially in a position shifted backwards compared to the standard position, and the vehicle occupant is a short and/or light person, the control unit only activates the foot airbag module (16) of the second restraint element (10).
