A vehicle load-limiting suspension apparatus comprises at least one shear tab for controlling an amount of impact load applied to a vehicle structure when a vehicle impact event occurs. The vehicle load-limiting suspension apparatus further comprises at least one crush tube for limiting the amount of impact load applied to the vehicle structure after the at least one shear tab shears in response to occurrence of the vehicle impact 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 force damper arranged to progressively arrest a first force imparted by an object moving in a first direction, the force damper including a housing, a driving member and first and second resilient members. The housing includes a first end and a second end, the first end having a first surface, a second surface opposite the first surface and a first connection point secured to the first surface, and the second end having a through bore and a third surface opposingly disposed relative to the second surface. The driving member includes a first end, a second end and a shaft therebetween, the first end having a stop and the second end having a second connection point. At least one of the first and second resilient members is formed from a material that at least partially undergoes plastic deformation when the first force is arrested. The first and second resilient members are disposed between the stop and the third surface and impart a second force on the stop toward the second surface.

The disclosed inventive concept provides a crushable air duct having formed thereon a series of strategically positioned and patterned crack-initiating grooves. The grooves allow the air duct to be crushed in an impact event and a specified impact force, thereby protecting adjacent and higher cost under hood components from damage. In an impact event, the series of grooves allows the cracks in the air duct to readily propagate throughout the pattern in a controlled and predictable manner. The crushable air duct is formed from a rigid polymerized material. The duct includes an inlet and an outlet. The grooves are formed on either or both the exterior surface and the interior surface of the duct. Some of the grooves extend generally between the inlet and the outlet. These grooves are preferably parallel. Other grooves are circumferentially formed around the duct. At least some of the parallel and circumferential grooves intersect.

A shock absorber system includes a body, a component, and at least one primary attachment that secures the component on the body. A secondary attachment is configured to secure the component to the body upon breakage of the primary attachment. The secondary attachment includes a single-use shock absorber and a cable that is attached to the body and secured through the single-use shock absorber to the component.

Aspects of the subject disclosure may include, for example, a helmet suspension system including a number of levers, wherein a first lever of the number of levers rotates about a fulcrum in response to an impact force of a collision between a helmet shell and a foreign object to obtain a lever response. The system includes a sacrificial assembly including a first deformable member, wherein the sacrificial assembly is in communication with a group of levers of the number of levers. A first strain applied to the first deformable member according to the lever response to obtain a first stress response of the first deformable member based on a first stress-strain relationship including a non-linear response. The first stress response of the first deformable member includes the non-linear response, wherein the first stress response reduces a portion of the impact force transmitted to a body of a user. Other embodiments are disclosed.

A backpack body has an openable accommodation chamber having a top opening. The accommodation chamber utilizes a restricting structure to position an energy absorption band. The energy absorption band includes a first layer and a second layer that are coincidingly bound. The top ends of the first and second layers extend first and second connecting portions respectively. The first and second connecting portions divergently protrude from the backpack body via the opening. The first connecting portion is configured for coupling with a safety harness, while the second connecting portion is for coupling with an anti-falling device. When the user falls, the falling makes the restricting structure release the first and second layers, so that the first and second layers leave the accommodation chamber via the opening for anti-falling suspension. Accordingly, the present invention has real improvements, including fine appearance, economic efficiency, and etc.

A vehicle body includes a structural member having an inner surface defining an elongated cavity. The structural member includes an outer panel member joined to an inner panel member. A reinforcement member is positioned in the cavity wherein a gap is provided between the reinforcement member and the inner surface of the structural member. The reinforcement member includes an outer section, an inner section and a tension web interposed between and contacting the outer section and inner section. The outer section faces the outer panel member and the inner section faces the inner panel member. The tension web is secured to the outer panel member and inner panel member. An adhesive secured to the reinforcement member is activatable to expand toward the inner surface of the structural member to define a joint between the reinforcement member and the structural member and to at least partially fill the gap.

A crash box may include one or more layers arranged to absorb crash energy. In some embodiments, the crash box includes a first layer having an outer skin defining a periphery of the first layer and at least one of: 1) a rib and web structure, and 2) an array of tubes disposed within the outer skin for absorbing crash energy, and a second layer adjacent to the first layer, the second layer having an outer skin defining a periphery of the second layer and at least one of: 1) a rib and web structure, and 2) an array of tubes disposed within the outer skin for absorbing crash energy.

A crash box for a vehicle, which mediates a back beam and a side member disposed in a width direction of the vehicle and absorbs crash energy when a crash occurs, may include a connecting body including a front coupling portion coupled to the back beam, a pair of side connecting portions bent from the front coupling portion to face each other, and a rear coupling portion extending from an end portion of each of the side connecting portions by being bent to be coupled to the side member; and a pair of connecting plates coupled to open upper and lower end portions of the connecting body, respectively.
