In some embodiments, an energy absorber element can comprise: a first support wall and a second support wall, a crush wall joining the first and second support walls together to define a deformable zone; a connection mechanism configured to connect the first and/or second support wall to a vehicle. In one embodiment, a method for using an energy absorber element in a vehicle can comprise: detachably connecting an energy absorber element to a vehicle at a support location for a vehicle component, once the energy absorber element has absorbed energy, detaching the energy absorber element from the vehicle; and separately replacing the energy absorber element from the vehicle component. In some embodiments, the vehicle component is not replaced.

A connecting element (3) for adjusting the height of a vehicle seat (1) includes an angular element (3.1) with a first leg (3.1.1) having a seat part side receiving opening (3.1.5) and an opposite rail side end receiving opening (3.1.4), and a second leg (3.1.2) angled relative to the first leg (3.1.1) and a tooth element (3.2). The seat part receiving opening (3.1.5) is situated in a connection area of the first leg (3.1.1) and of the second leg (3.1.2). The tooth element (3.2) has a first section (3.2.1) configured as a circular arc with toothing (V2) that is connected at an end side to the second leg (3.1.2) and a second section (3.2.2) that is angled from the first section (3.2.1) in the direction of the receiving opening (3.1.5) on the side of the seat part and is connected to the first leg (3.1.1) at the end side.

A vehicle-mounted seat device includes an SB main frame, a backrest, an SB subframe, and one or more front-back position regulation mechanisms for regulating the position of the SB subframe in the front-back direction relative to the SB main frame. Each front-back position regulation mechanism includes a front restraining bracket secured relative to the SB main frame, a rear restraining bracket secured on the SB subframe, and a front-back wire strung between the front and rear restraining brackets. The rear restraining bracket is deformed such that its front end portion is displaced rearward relative to its end portion upon input of a load greater than a predetermined load. A maximum pulling load of the front-back wire is greater than a load that causes initial deformation of the rear restraining bracket.

The vehicle seat back according to the invention includes a textile assembly (30) having at least one embrittled linear zone (32, 32A, 32B) able to tear during an impact of the head of a passenger located on the seat behind the seat back considered, so as to enable rocking of this passenger's head to be continued and, at the same time, to be slowed down. Application to aircraft seats.

A seat for vehicles includes: a seat back frame; and a pressure receiving member that is mounted on the seat back frame to support a back of an occupant. The seat back frame includes a lower seat back frame and an upper seat back frame mounted on an upper portion of the lower seat back frame in a forwardly and rearwardly swingable manner, and the pressure receiving member is disposed from an area corresponding to the shoulder of an occupant to an area corresponding to the waist of the occupant and is supported by the upper seat back frame.

A seat-back adjustment system for a seat for a vehicle may include a frame member configured for attachment to a support structure of the vehicle, and a rack arrangement movably attached to the frame member. The rack arrangement may include an adjustment rack and a locking rack. A driving arrangement may include at least one gear intermeshing with the adjustment rack and operable to move the rack arrangement relative to the frame member, and a locking arrangement may include at least one locking element operable to engage the locking rack when the vehicle experiences at least a predetermined negative acceleration.

A seat assembly for a vehicle includes a seat frame. The seat assembly includes an armrest. A hinge pivotally connects the armrest to the seat frame. The armrest includes an upper extension extending upwardly from the hinge and a lower extension extending downwardly from the hinge. The seat assembly includes a deformable member between the seat frame and the lower extension of the armrest. The deformable member is deformable relative to the seat frame and the armrest.

Arrangements for safety and comfort in vehicles.

Active noise control systems and methods are disclosed that include generating with a first sub-system, anti-noise that is configured to reduce or cancel noise occurring at a listening position. Generating with a second sub-system, anti-noise that is configured to reduce or cancel noise occurring at the listening position. The first active noise control sub-system has a higher robustness than the second active noise control sub-system.

A seating assembly for a vehicle includes a seat having a seat cushion assembly. A seatback is pivotally coupled with the seat and includes a seatback cushion assembly. A polymeric hard back panel is operably coupled with the seatback and includes a recessed portion. A controlled deformation portion includes a rupture line configured to split during a rear impact collision of the vehicle, resulting in flaps of the controlled deformation portion extending rearward relative to the seatback. The controlled deformation portion is generally concealed from rearward view by a pocket wall.
