A seat sliding structure for a vehicle includes: a pair of left and right slide rails that include upper rails, which are attached to a lower portion of a vehicle seat, and lower rails, which support the upper rails such that the upper rails can slide in a vehicle longitudinal direction; rail guiding members that are fixed to a floor panel, and that support the lower rails such that the lower rails can slide in the vehicle longitudinal direction between a driving position at a vehicle front side and a relaxation position at a vehicle rear side; and a locking mechanism that locks movement of the slide rails at the relaxation position, and that releases a locked state when a frontal collision of the vehicle is detected or predicted.

The present disclosure relates to a vehicle seat that includes a seat cushion which is substantially horizontal with respect to a floor of a vehicle. The vehicle seat further includes a seat back including a proximal end and a distal end separated by a longitudinal length, such that the proximal end is pivotably coupled to the seat back. The vehicle seat also includes a track arranged adjacent to the seat cushion and the track has a longitudinal length. The track includes a proximal end and a distal end, such that the proximal end of the track is attached to a biasing element while the distal end of the track is attached to a portion of the seat back. In a crash event, the seat back is displaceable with respect to the seat cushion along the longitudinal length of the track.

Disclosed is a seat rail pair (2) for adjustment of a vehicle seat (8), in particular of a motor vehicle seat, in an adjustment direction (x), comprising a guide rail (10) extending parallel to the adjustment direction (x) for fastening to a vehicle floor, and a fastening rail (21), which is adjustably guided on the guide rail (10) in the adjustment direction (x) for fastening the vehicle seat (8), wherein an energy absorber element (5) is provided in a path, which introduces the force acting on the vehicle seat (8) into the vehicle structure, which energy absorber element permits a movement of the vehicle seat in the adjustment direction (x) under plastic deformation when a predetermined value of the force is exceeded.

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.

An active head restraint for a seating assembly of a motor vehicle comprises a structural support for a seatback of the seating assembly, a movable head restraint pad having a stowed position and a deployed position, and a linkage deployment mechanism. The linkage deployment mechanism comprises an upper and lower bar pivotally attached at a forward end to a rear surface of the movable head restraint pad and pivotally attached at a rearward end to an outer tube fixed to an upper portion of the structural support. An inner tube reciprocates within the outer tube. A trigger mechanism is operatively connected with a lower end of the inner tube and urges the inner linkage and an actuating link to a raised deployed position in response to a rear impact event. The actuating link applies an upward force to the lower bar to deploy the movable head restraint pad.

A vehicle seat to be mounted on a vehicle includes a seat cushion and a seat surface lowering mechanism. The seat cushion includes a seat surface on which a waist of an occupant of the vehicle is to be placed. The seat surface lowering mechanism is configured to lower the seat surface in response to either one of an occurrence of a rear-end collision of the vehicle or a sign of the occurrence of the rear-end collision.

A seat installation for a combat vehicle which protects an occupant from the effects of an explosion detonated beneath the vehicle in which breakaway structures are interposed between a seat pan and the vehicle floor which initially rapidly drives the seat up after the explosion, but which quickly breaks away to avoid spinal compression injury. A crushable energy absorbing structures thereafter absorb the floor motion, each structure comprised with a vertical stack of crushable energy absorbing cells which are successively crushed at higher force levels to adapt the seat installation to varying weight occupants. A pivoted foot rest provides spaced above the floor which mitigates injuries to the feet and legs by allowing the feet to avoid contact with the floor and which swing up and away from the floor while avoiding tipping of the seat.

The transport vehicle seat allows to avoid the violent collision of a passenger's head located on the seat placed behind and to dampen the violent forward rocking of this passenger, in case of a frontal collision of the transport vehicle. The seat includes a pivotably mounted fold-down element (10), such as a table, placed on the rear face of a seat back. It has blocking part (14) holding the fold-down element (10) in a substantially vertical position, blocking part (14) being able to break off during a collision applied to the fold-down element (10) and to allow the latter to go on rocking towards the back seat to which it is attached. Application to aircraft seats.

A dual switch arm and mode select system for monitoring an ejection mode selection of an ejection system may include a controller. An ejection mode selector, a first arm switch assembly, a second arm switch assembly, and a display may be in communication with the controller. The controller may determine an ejection mode of the ejection system based on a signal received from the ejection mode selector. The controller may determine a position of the first arm switch assembly and a position of the second arm switch assembly. The controller may command the display to output at least one of a fault-free signal, a fault signal, or a warning signal based on the ejection mode and the positions of the first arm switch assembly and the second arm switch assembly.

An assembly for absorbing energy in an overload event has an energy absorber for reducing the load on an object being transported on a loading unit. The energy absorber, in the case of a one-off overload event with an energy input that is sufficiently high that damage to the object would be possible or highly likely in the absence of the energy absorber, to absorb energy in order to reduce the load on the object. Measured values relating to the current state of the loading unit are periodically acquired by a sensor device. A control device identifies an overload event from the acquired measured values. A weight of the object to be transported and a limit value for a load on the object are determined. Following identification of the overload event, damping by the energy absorber is controlled to keep the load on the object below the limit value.
