The invention relates to a damping member (1), comprising at least two engagement points (2), the damping member (1) having an absorption means that acts elastically, wherein fastening elements (3) are arranged on the damping member (1) and wherein the damping member (1) is designed to be deformable.

A vehicle seat arrangement in a vehicle is disclosed. The vehicle seat arrangement comprises a vehicle seat with a back portion and a seat portion, said seat portion comprises a front section, adapted to support legs and knees of a user, and a rear section adapted to support the user's weight. The rear section of the vehicle seat comprises a deformation unit adapted to reduce the force exerted on the user during a crash, the force being absorbed through plastic deformation of a deformation portion. The deformation portion is adapted to deform with a linear deformation property of the energy absorption, after a force threshold is exceeded. A vehicle comprising such a vehicle seat arrangement, and a method used in said vehicle seat arrangement are also disclosed.

A vehicle seat includes a seat bottom, a seat back coupled to the seat bottom, and an immobilization system coupled to the seat bottom and the seat back to immobilize an occupant. The immobilization system includes at least one bottom strap kit operatively attached to the seat bottom and at least one back strap kit operatively attached to the seat back at predetermined locations with each of the at least one bottom strap kit and the at least one back strap kit including a strap having a stowed position hidden from view and a deployed position visible to secure an occupant in a seated position against the seat bottom and the seat back.

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.

A vehicle seat mounting system for mounting a vehicle seat to a vehicle chassis includes a first mounting arrangement with a first chassis attachment portion configured to fixedly connect to the vehicle chassis and a first seat attachment portion configured to fixedly connect to the vehicle seat. The first seat attachment portion is movable relative to the first chassis portion in at least one direction. The first mounting arrangement further includes a compressible member interposed between the first chassis attachment portion and the first seat attachment portion. The compressible member is configured to absorb impact forces between the vehicle chassis and the vehicle seat.

A seat impact energy absorbing system having an energy absorbing module that limits forces transmitted through the seat to its occupant. Such forces may emanate from, for example, a land mine detonation. The module has frustoconical structures joined by hollow interconnecting ribs that create support pillars there between. At least some of the support pillars have tops.

In one embodiment there is disclosed an energy attenuating vehicle seat. The seat includes 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 device extends between the seat back longitudinal members and the seat pan longitudinal members and is pivotally attached to the seat pan and the seat back allowing individual adjustment of the back or pan. 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 (G force and Pressure Wave) due to accident or explosive events and is capable of automatically resetting.

The present invention relates to a vehicle seat system for reduction of vertical peak acceleration of a person seated in a vehicle seat during impact. The vehicle seat system comprises a seating structure and a trim at least partially enclosing the seating structure. The trim is releasably fastened to the seating structure by means of interconnected trim fastening means comprising at least two parts adapted to release from each other when the vertical peak acceleration exceeds a predetermined limit value, subsequently reducing the vertical peak acceleration. The present invention further relates to a vehicle comprising the vehicle seat system.

Methods and apparatus are provided for a shock attenuation device configured to operate between a structure and a mass that is supported by and moveable relative to the structure in a guided manner along a stroking direction. In one embodiment, a notch load portion is configured to provide a resisting force to relative displacement of the supported mass over a first stage stroking distance according to a predefined load profile that includes a spike load peaking at a first threshold load value at the onset of relative displacement, and a substantially constant notch load for a remainder of the first stage stroking distance. A constant load portion arranged serially with the notch load portion is configured to provide a substantially constant resisting force to displacement of the supported mass at a second threshold load value over a second stage stroking distance, wherein the second threshold load value is higher than the first threshold load value.

A method and apparatus for protecting a passenger during a crash comprises a moveable seat with an energy absorber (EA) that allows the seat to stroke a finite distance to decelerate the passenger in a controlled manner. The seat is designed so that one of a plurality of fixed profile EA's can be selectively engaged to provide a tailored EA composite profile adapted to the occupant's weight and anticipated crash environment. The tailored EA composite profile applies a frequency matched, low onset force to the seat, which substantially eliminates problems associated with dynamic overshoot of the passenger's spine.
