A strengthening structure of a vehicle is provided herein and includes a base having cutouts. Relief members are disposed across the base and each include a cross section having twelve or fourteen corners, a distal end, and an open proximal end in communication with a corresponding cutout.

A vehicle includes a passenger compartment having a roof structure having a front header, a pair of side headers and a rear header. A headliner is disposed beneath the roof structure. At least one inflatable bladder is disposed along at least one of the front header, the pair of side headers and the rear header. The at least one inflatable bladder is connected to an inflator. A rib structure is disposed adjacent to the at least one inflatable bladder. The inflatable bladder inflates to a maximum height of 12 cm below the at least one of the front header, the pair of side headers and the rear header.

Provided is a damping member for a vehicle having excellent efficiency of input energy absorption. A damping pad serving as a damping member for a vehicle includes a base plate portion having a flat plate shape, a vertical wall arranged at a rim of the base plate portion in a flange-like manner, a plurality of ribs arranged in parallel as rising from the base plate portion, each of the ribs connected to a vertical wall as extending in a direction intersecting with the vertical wall, and a fragile section arranged between adjacent two of the ribs. The fragile section includes a groove formed at the vertical wall and a slit formed at the base plate portion.

A roof system for a vehicle includes a fixed roof element, forming a fixed roof segment of a vehicle roof bounding a passenger compartment and situated in a rear area of the vehicle roof, a roof opening and closing mechanism, which is designed to allow a relative movement of a movable roof element in relation to the fixed roof element for the opening and closing of a roof opening in the vehicle roof and/or a relative movement of a movable roller blind in relation to the vehicle roof. The fixed roof element is designed as a single-piece roof element having at least one impact energy absorption section and at least one receiving section locally distinct from the impact energy absorption section for receiving of electrical and/or mechanical function elements, by which or in the interplay of which with other function elements a movement of the movable roof element for the opening and closing of the roof opening and/or a driving of the roller blind can be effectuated.

A strengthening member for an automobile includes a cellular structure having a plurality of cells. A cross section of each cell has eight sidewalls interconnected at eight corners to define a closed polygon. The sidewalls define eight internal angles located at the corners. Two of the internal angles are acute and two of the internal angles are reflex.

A strengthening structure of a vehicle is provided herein and includes a base having cutouts. Relief members are disposed across the base and each include a cross section having twelve or fourteen corners, a distal end, and an open proximal end in communication with a corresponding cutout.

An energy absorbing material includes a multi-cellular structure formed from a plurality of interconnected cells having a lattice structure. Each of the plurality of interconnected cells includes at least four nodes and at least one lattice element extending between each of the at least four nodes. The at least one lattice element has a diameter no greater than 2.5 mm.

Composite structures include composite cellular or foam structures and more specifically composite cellular or foam structures used for protective head liner structures (e.g. in helmet liners).

A roof-mounted energy absorbing countermeasure system for use in a vehicle is provided. In one example, the system may include an impact detection module configured to detect whether a vehicle has experienced an impact and generate an impact detection signal in response thereto. The system may also include a countermeasure disposed between an outer roof panel of the vehicle and an inner roof panel of the vehicle. The outer roof panel and the inner roof panel may be separated by a first distance in a pre-impact state. The countermeasure may be configured to deploy, in response to generation of the impact detection signal, so as to cause at least a portion of the outer roof panel and at least a portion of the inner roof panel to be separated by a second distance that is greater than the first distance.

An airbag device for a panorama roof may include: a roller disposed under a panorama roof and having a blind wound therearound, the blind serving to cover the panorama roof; a head liner covering the roller; an inflator disposed at sides of the panorama roof; a guide tunnel connected to the inflator to guide gas; and a cushion connected to the guide tunnel, and deployed by gas guided through the guide tunnel so as to cover the panorama roof.
