An assembly for a vehicle includes a vehicle roof and a headliner supported by the vehicle roof. The assembly includes an energy absorber between the headliner and the vehicle roof. The energy absorber includes a wall extending transversely to the headliner and the vehicle roof. The wall includes a lattice structure including a repeating pattern of strips and open cells.

A roof airbag for vehicles is proposed. The roof airbag includes: a main chamber configured to be deployed as gas is introduced therein through a diffuser; an overlap chamber into which the gas is introduced and configured to be deployed into a shape that overlaps the main chamber around the diffuser; and a support chamber into which the gas is introduced and configured to be deployed while overlapping a roof frame.

A roof airbag apparatus may include: a first-row deployment part deployed from the front to the rear of a roof so as to cover a front area, when gas is supplied from a gas supply part; a second-row deployment part coupled to a front end of the first-row deployment part so as to communicate with the first-row deployment part, and configured to cover a rear area which is deployed to the rear when the first-row deployment part is deployed; and an auxiliary deployment part coupled to a top or bottom surface of the first-row deployment part so as to communicate with the first-row deployment part, and configured to increase/decrease the top-to-bottom thickness of the first-row deployment part, when deployed.

An assembly for a vehicle includes a vehicle roof and a panel rotatably connected to the vehicle roof. The panel is rotatable away from the vehicle roof from a stowed position to a deployed position. The assembly includes an airbag supported on the panel. The airbag is inflatable from the panel in a vehicle-forward direction when the panel is in the deployed position.

A closing device for opening and closing an opening in a vehicle is disclosed. The closing device comprises a closing system, having a closing body (SK) that is fitted on the vehicle (FZ) in a movable manner and is configured to open and close the opening (O), a drive device (AV) that is operatively connected to the closing body (SK) and is configured to move the closing body (SK), and a transmission system (US) that is arranged between the closing body (SK) and the drive device (AV) and is configured to transmit a drive force generated by the drive device (AV) to the closing body (SK). The closing system (SLS) has a closing system spring rate (FRSLS) that characterizes an overall elasticity of the closing body (SLS), of the drive device (AV) and of the transmission system (US). The closing device (SV) also comprises a force transmission spring unit (KUFE) that is configured to pick up the drive force transmitted from the drive device (AV) to the closing body (SK). The force transmission spring unit (KUFE) has a force transmission spring rate (FRKUFE) that is lower than the closing system spring rate (FRSLS).

The safety restraint system for motor vehicles, arranged in the roof lining of the vehicle, comprising an elastic wall (1), brackets (2), a gas generator consisting of an inflator, and a control electronics with impact sensors, the essence of which consists in that, that a folded elastic wall (1) is connected under the roof of the vehicle to at least two brackets (2), consisting of a double strip of plastic film and/or elastic textile, when the said brackets (2) consist of a system of tightly into each other inserted extension parts forming a solid bracket (2), whereby an assembly of the folded elastic wall (1) and brackets (2) is arranged in a roof housing (3), and such roof housing (3) is attached under the roof of the vehicle. Both upper edges of the folded elastic wall (1) are firmly attached to the first, upper, solid part (21) of the bracket (2), arranged in the roof housing (3) nearest to the roof lining of the vehicle and firmly connected to this roof housing (3), whereby the double strip of the plastic film and/or elastic textile, forming the elastic wall (1), is on its lower side closed by means of a weld seam and/or a sewn seam to create a closed interior space with the front and rear wall, a bag, in which the brackets (2) are arranged and guided. The brackets (2) are deployed upon activation after an impact of the vehicle on the command of the control electronics with impact sensors by the gas pressure triggered from the gas generator, the inflator; and the mechanical movement of the system of tightly into each other inserted extension parts, forming a solid bracket (2), deploys the elastic wall (1) from a plastic film and/or elastic textile to the maximum, and thus the shape of the elastic wall (1) stretches appropriately and becomes solid. Thus formed elastic wall (1) greatly reduces the forward movement path of the head, and so it reduces the load on the vertebras and prevents contact with a solid obstacle.

A module for a vehicle including a roof and a cabin includes a housing defining a chamber and having an opening in fluid communication with the chamber. The housing is configured for placement in the roof. An airbag is provided in the chamber and is inflatable to a deployed condition extending through the opening into the cabin. A door pivotably connected to the housing closes the opening. The door is pivotable away from the roof in response to deployment of the airbag to provide a reaction surface for the deploying airbag. The door has a first length while closing the opening and a second length greater than the first length when pivoted away from the roof.
