A compound energy absorption system for a steering column may include different first and second energy absorption mechanisms. The first energy absorption mechanism may involve a slide that deforms a deformation strip in a crash event. The second energy absorption mechanism may involve an energy absorbing strap and a carrier, with the energy absorbing strap being configured to bend and/or tear in a crash event. The energy absorbing strap, the carrier, the deformation strip, and the slide may be packaged compactly in series along an inner jacket tube of the steering column such that the carrier and the deformation strip move relative to the slide and a portion of the energy absorbing strap in a crash event. A pyrotechnic switch, a solenoid, or the like may selectively couple or decouple the second energy absorption mechanism depending on the severity or anticipated severity of a crash event.

To increase a compactness of damping systems intended to operate in the event of a dynamic landing of an aircraft, a damping system comprises a primary damper device and a secondary damper device. The primary damper device comprises at least one beam, each beam extending along a direction of a longitudinal axis. The damping system is configured so that at rest, the primary damper device has a stiffness greater than a stiffness of the secondary damper device in the direction of the longitudinal axis. When a force is applied to the damping system along the direction of the longitudinal axis, with a value less than a limit value, each beam remains in a compression state. When the force applied has a value greater than or equal to the limit value, each beam undergoes buckling and the secondary damper device undergoes elastic deformation.

A modular shock absorber developed for use in places where shock absorption is required. The modular shock absorber includes; horizontal carriers, a main carrier I and a main carrier II, a central carrier I, a central carrier II, an upper plate I, a lower plate I, a lower plate II, an upper plate II, an upper plate III, a lower plate III, a lower plate IV and an upper plate IV.

A steering column assembly includes a lower jacket assembly extending longitudinally from a first end to a second end and having an energy absorption (EA) plate. The steering column assembly also includes an upper jacket assembly at least partially received within the lower jacket assembly. The steering column assembly further includes an energy absorption strap integrally formed with the lower jacket assembly.

An energy absorption device for a steering column for a motor vehicle includes an energy absorption element for absorbing energy by a relative movement between at least two components of the steering column in a crash situation, and at least one arresting element for arranging in a blocking position for blocking the relative movement.

A landing gear includes a pair of skids, a cross tube and a stiffening portion. The pair of skids is arranged in parallel with a front-rear axis of an airframe of a rotary wing aircraft. The cross tube is attached to the airframe and coupling the pair of skids to each other. The cross tube includes curved portions located closer to end portions of the cross tube than to portions of the cross tube attached to the airframe. The stiffening portion suppresses flattening of the cross tube and is arranged in at least one of internal spaces of the curved portions or a stiffened portion located between a pair of curved portions. The stiffening portion includes an enlarged diameter portion which increases in diameter by an axial fastening power acting in an axial direction of the cross tube, and a fastening portion configured to generate the axial fastening power.

A lattice structure and system for absorbing energy, damping vibration, and reducing shock. The lattice structure comprises a plurality of unit cells, each unit cell comprising a plurality of rib elements with at least a portion of the rib elements including a solid bendable hinge portion for converting energy into linear motion along a longitudinal axis of the respective rib element.

A footrest support structure includes a footrest main body 10 on which a foot of an occupant is placeable, a panel member 14 of a vehicle interior floor, and a shock absorbing member 15. The panel member 14 has an inclined portion 14b inclined forward and upward from the horizontal portion 14a. The shock absorbing member 15 is interposed between the panel member 14 and the footrest main body 10. The inclined portion 14b of the panel member 14 has a recessed portion 18 that is recessed downward. The shock absorbing member 15 has a thinned portion 21 in a portion facing the recessed portion 18, which is thinner than other portions. A deformation-allowing space 30 is formed between the recessed portion 18 and the shock absorbing member 15.

In a table device (100) with a tabletop (110), which is coupled to a support strut (120) for mounting on a wall for purposes of a support, a danger of injury to a person located in its vicinity during a sudden acceleration, especially in the direction of travel, is significantly reduced as compared to the known table devices (110) in that the tabletop (110) is fastened to a carrier platform (140) provided with mechanical damping elements (130, 131; 130, 131) and is indirectly connected to the support strut (120) across the mechanical damping elements (130, 131; 130, 131).
