A seat mounting system includes a seat frame having a support surface and first and second side surfaces downwardly extending from opposed sides of the support surface. Mounting members are supported on the first and second side surfaces. The mounting members each include an inner layer, an outer layer, and a deformable core portion disposed therebetween. The mounting members each include a mounting aperture extending through the deformable core portion, such that the deformable core portion surrounds the mounting aperture. A base frame includes a receiving aperture disposed through a body portion of the base frame. The base frame is operably coupled to the seat frame by a fastener received through the receiving aperture of the base frame and further received through the mounting aperture of the mounting member.

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.

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 mount assembly for mounting a cabin attendant seat to a support structure may comprise a first strap configured to plastically deform in response to a deflection of the support structure. The first strap may comprise a first perforation, a second perforation, and a third perforation located between the first perforation and the second perforation. The perforations may be configured to allow the strap to plastically deform.

A pneumatic seat support by itself supports a seat above a floor of a vehicle. The pneumatic seat support has upper and lower air chambers. The lower air chamber is a rigid cylindrical tube. The upper air chamber is a flexible cylindrical bellows, with a diameter greater than the diameter of the tube. Three or more linear shafts extending through the upper air chamber and into the lower air chamber provide a single-degree-of-freedom bearing support structure that allows vertical motion of the seat but withstands horizontal loads on the seat. When the seat moves vertically downward, it compresses air in both chambers, providing a seat support system with a natural oscillation frequency which is less than 2.4 Hz, and preferably in the range of 1.5-2.2 Hz.

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.

A seat bottom assembly including a seat bottom frame having a front side and a back side, a seat plate having a front side and a back side, webbing stitches, and tear away stitches. The back side of the seat plate is coupled to the back side of the seat bottom frame. The webbing straps are coupled to and extending between the front side of the seat bottom frame and the front side of the seat plate, and tear away stitches connect two points of the webbing straps along a longitudinal axis so that the webbing straps are partially looped at locations of the respective tear away stitches. The tear away stitches separate and increase a length of the webbing straps in response to experiencing a threshold load in a direction perpendicular to the seat plate.

A seat mounting system includes a seat frame having a support surface and first and second side surfaces downwardly extending from opposed sides of the support surface. Mounting members are supported on the first and second side surfaces. The mounting members each include an inner layer, an outer layer, and a deformable core portion disposed therebetween. The mounting members each include a mounting aperture extending through the deformable core portion, such that the deformable core portion surrounds the mounting aperture. A base frame includes a receiving aperture disposed through a body portion of the base frame. The base frame is operably coupled to the seat frame by a fastener received through the receiving aperture of the base frame and further received through the mounting aperture of the mounting member.

A damping member (1) which has at least two engagement points (2), wherein the damping member (1) has an absorption means, wherein fastening elements (3) are arranged on the damping member (1), and wherein an additional absorption means (4) is provided which brings about shock absorption together with the absorption means.

The invention relates to a damping member (1) which has at least two engagement points (2), wherein the damping member (1) comprises at least one spring element (3), the spring elements (3) have an absorption means, the spring elements (3) have a curved shape (4), and the curved shape (4) of the spring elements (3) has a recess (4) which enables the spring elements (3) to be deformed.
