Abstract: Various implementations include a battery disconnect device that includes a breaker, a housing, and a bus bar. The breaker has a pivot portion and an actuation portion, and the actuation portion has an actuation face. The pivot portion has an axis of rotation about which the breaker is pivotable. The housing defines a chamber, and the chamber is in fluid communication with a gas generator via an inlet defined by an inlet wall of the housing. The breaker is disposed within the chamber in a first position in which the actuation face is adjacent the inlet and inlet wall and combustion gas from the gas generator pushes on the actuation face to cause the breaker to pivot about the axis of rotation of the pivot portion to a second position, which causes the breaker to break the bus bar.

Abstract: Various implementations include a linear actuator that provides controllable depressurization of the actuator and is tunable to the specifications set by the vehicle manufacturer. The linear actuator includes a housing and a piston and piston rod that are slidably disposed within a channel extending through the housing. The piston rod defines a vent path that includes an axial cavity adjacent the proximal end of the piston rod and radial channel extending from the axial cavity to an outer peripheral surface of the piston rod. Pressurized gas entering the housing causes the piston to move axially through the housing, and a portion of the gas vents through the cavity and radial channel to the channel of the housing and then to the environment. This venting allows the actuator to be returned to its initial or stored position within a time frame and without exceeding the force set by the manufacturer.

Abstract: A hood lifting mechanism according to various implementations includes a housing and a piston. A distal end of the piston is urged away from a distal end of the housing to lift a hood upwardly away from a vehicle body in response to the vehicle hitting a pedestrian. To prevent the piston from rattling or moving within the housing while in a stored position, a portion of the piston and a portion of the housing form an interference fit in the stored position. A gas generator in fluid communication with a proximal end of the housing provides sufficient force to overcome the interference fit and urge the distal end of the piston out of the housing.

Abstract: A gas generator contains an anti-vibration, auto-igniting pad. The pad is formed from a mixture of a known auto-igniting composition mixed with an elastomeric polymer, and then cured, thereby forming a polymer—auto-igniting composition matrix. The pad is placed in thermodynamic communication with a housing on the gas generator, thereby enhancing the safety of the gas generator while yet providing a multi-functional pad. The pad is formulated to reduce vibrations when biased against an associated gas generant, while augmenting the amount of gas produced upon gas generator activation, while yet providing an auto-igniting material that is ignited during a high heat event.

Abstract: Systems and methods of printing sensor loops on a sensor mat for use in a steering wheel are disclosed herein. For example, the sensor mat may include a base substrate, one or more printed sensing loops, and an insulating material. The printed sensing loops are made with conductive ink that is disposed upon the base substrate or the insulating layer from a print head and adheres thereto. These sensor mats are versatile with respect to the type of base substrate and insulating materials that may be used, the shape of the sensing loops, and the area each loop may occupy. Shielding loop(s) may also be printed adjacent the sensing loop(s). This configuration allows shielding for the sensing loops as part of the sensing mat, which may reduce the thickness of the steering wheel rim and manufacturing and installation times.
