A protective member such as a helmet includes an outer layer and an inner layer interconnected by multiple connectors, such as extension springs, under tension along their longitudinal axis. The connectors absorb energy from an impact force by resisting further tension along their longitudinal axis and allow the outer layer and inner layer to move relative to each other. In the helmet application, the head of a user experiences less impact force, reduced change in momentum or position of the head and neck, reduced head and neck loads and reduced amounts of linear and rotational acceleration. The protective member can be used in numerous applications and environments, including for participants in sports, in applications including bumpers, passenger cabins, car seats and beds.

A pedestrian protection apparatus for a motor vehicle is disclosed. The apparatus includes a catcher beam and a catcher beam support assembly including a catcher beam support to which the beam is attached. The support is movable between stowed and deployed positions. The apparatus includes a bumper energy absorber and a bumper beam. The assembly is positioned adjacent the absorber and is either substantially within or adjacent to the bumper beam. The apparatus includes a mechanical, electromechanical or pneumatic actuator to allow the support to move to its deployed position. A pedestrian impact sensor sends a signal to a control unit in the event of an imminent pedestrian impact. The control unit then signals the assembly to allow the catcher beam to move to its deployed position using the actuator. In the event of a false positive deployment, the actuator retracts the catcher beam to its stowed position.

A pedestrian impact sensor sends a signal to a control unit in the event of an imminent pedestrian impact. The control unit then signals the assembly to allow the catcher beam to move to its deployed position by the use of the actuator. In the event of a false positive deployment, the actuator retracts the catcher beam to its stowed position.

A circuit mounting assembly includes a housing and a protrusion extending from the housing. At least one retaining member is attached to the protrusion and adapted to deform when received in an opening of a mounting structure and form an interference fit with the mounting structure so as to hold the housing to the mounting structure. At least one attachment member provides a secure attachment of the housing to the mounting structure. Electrical circuitry is located within the housing for performing a function, and an electrical connector for providing an electrical connection between the electrical circuitry located within the housing and an external device.

A collision detection device includes a chamber member, a pressure sensor, a collision detection ECU, and a projecting portion. The chamber member is disposed on a vehicle-front side of a bumper reinforcement in a bumper cover and includes a chamber main body having therein a hollow portion. The pressure sensor detects pressure in the hollow portion of the chamber main body. A clearance is formed between the chamber member and a front surface of the bumper reinforcement at least on a part of a rear surface of the chamber main body. The collision detection ECU detects a collision of an object with the bumper cover based on a pressure detection result by the pressure sensor. The projecting portion is provided to project from the rear surface of the chamber main body, and an end of the projecting portion is in contact with the front surface of the bumper reinforcement.

An obstacle detection device includes an air-coupled ultrasonic wave sensor 2 mounted into a penetrating hole 11 of a mounting member 1 with an emitting surface 21a being oriented towards outside the obstacle detection device, and an acoustic matching layer 3 fixed to the emitting surface 21a, to achieve matching between the acoustic impedance of the air-coupled ultrasonic wave sensor 2 and that of the air, in which microcapsules 31 are added to the same material as that of the mounting member 1.
摘要:
A sensing and injury mitigation system for a vehicle to identify an object in an impact event is disclosed. The system includes an impact sensing unit comprising an impact sensor and a pressure sensing unit. The impact sensor has fluid-filled first and second tube portions. The pressure sensing unit has a housing and first and second pressure sensors located within the housing. The first tube portion of the impact sensor is attached to the first pressure sensor and the second tube portion of the impact sensor is attached to the second pressure sensor. The pressure sensing unit senses changes in fluid pressure within the tubes. In one embodiment, the tube portions of the impact sensor define a loop. In another embodiment, at least a portion of the first tube portion and at least a portion of the second tube portion share a common axis.
