A shock mitigation seat 10 including a plurality of individual shock absorbing members 16 resilient to compression from a shock impact, the shock absorbing members 16 being positioned one adjacent another and such that at a certain stage of compression an individual shock absorbing member 16 resiliently deforms and comes into contact with one or more adjacent individual shock absorbing members 16 which thereby increases resistance to further compression.

A vehicle assembly includes a vehicle body including an interior panel, a seat having a frame fixed to the panel, and a seat energy absorber operably associated with the seat and including a backing and a bracket. The backing is formed from the vehicle body and positioned separated from the seat to define a space between the seat and the backing along a length of the panel, and the bracket is mounted in the space on at least one of the seat and the backing such that a proximal end portion of the bracket is located closer to the seat than the backing, and a distal end portion of the bracket is located closer to the backing than the seat. During a crash event a section of the panel is configured to collapse against the seat when the seat is driven toward the panel relative to the vehicle body.

The present invention relates to an energy absorption device for a seat of an aircraft, in particular of a helicopter, with at least one impact mechanism (2, 4) and at least one energy absorber (1) coupled with the impact mechanism (2, 4), wherein the impact mechanism (2, 4) acts on the energy absorber (1) for the energy absorption at least in the case of a crash.

A shock mitigation seat 10 includes a plurality of individual shock absorbing members 16 resilient to compression from a shock impact. The shock absorbing members 16 are positioned one adjacent another and such that at a certain stage of compression an individual shock absorbing member 16 resiliently deforms and comes into contact with one or more adjacent individual shock absorbing members 16 which thereby increases resistance to further compression. The seat may be incorporated in a shock mitigation system 50 which has at least one sensor operable to detect a force and to provide a feedback signal indicative of the nature of the force and a memory record the incidence and severity of these forces and provides an indication of cumulative forces absorbed

A seat having a seat back pivotally connected to a seat pan, the seat back and the seat pan independently pivotal. At the pivot between the seat back and the seat pan there is a rotary energy attenuation device. The rotary energy attenuating device cooperates with a track system along the length of seat longitudinal members allowing for different directions of travel and height adjustment. The vehicle seat offers passive or active protection from impact and sudden acceleration due to accident or explosive events and is capable of automatically resetting.

A passenger restraint system for roller coasters, designed to maintain a passenger in an essentially upright posture, the passenger restraint system including a fixed column and a seat column designed to support and hold the passenger, which seat column is coupled to the fixed column so as to be movable relative to the fixed column and to be adjustable to the size of the passenger during an embarkation phase. The seat column is coupled to the fixed column by an articulated linkage, and the passenger restraint system further includes a device for balancing the seat column, which balancing device includes a cylinder fixed, at a first articulated end, to the fixed column and, at a second articulated end, to the seat column.

Controlled energy absorption of seats for impact is described herein. One disclosed example method includes determining a weight of an occupant of a seat of an aircraft, and calculating, using a processor, a stroke load of a seat energy absorber operatively coupled to the seat based on the weight of the occupant. The example method also includes setting the seat energy absorber to the calculated stroke load.
