A coil spring for use in a cavity, such as in a groove of a pin, a housing, or both. The cavity can also be part of a seal assembly. The coil spring can have a longitudinal component positioned within the plurality of interconnected coils that runs along the spring coil axis in order to increase rigidity of the coil spring. The longitudinal component applies a load against the coil spring and/or provides restriction against the coil spring taking a shape or size different than that of the coil spring retaining groove.

A spring assembly of a hinge assembly for a closure panel of a vehicle, the spring assembly comprising: a spring support bracket for connecting to a bracket of the hinge assembly; a spring mounted on the spring support bracket, the spring having an output end, the spring for biasing operation of the hinge assembly in order to move the closure panel towards an open position, the spring assembly including a holder mounted on the spring support bracket such that the holder is movable between an engaged position with the output end and a disengaged position with the output end; wherein when the output end is engaged with input end, the spring assembly is mountable to the hinge assembly.

A coil spring has longitudinal component, located within the coil spring, running along the direction of a longitudinal axis of the coil spring. The longitudinal component may be a simple loop or may bias the coil spring into a different shape. The longitudinal component may have a first end and a second end, which may be connected. The first end, second end and longitudinal component may be in the same plane throughout the length of the longitudinal component. The longitudinal component may have a first end equipped with a first locking element and second end equipped with a second locking element. The first locking element may comprise a recess for accommodating a second locking element. The longitudinal component may be a metal wire and/or formed as a single piece. The coil spring may be part of a connector part connected with a mating connector part.

An electric brake actuator configured to push a friction member onto a rotary body by advancing a piston by rotating an input shaft by an electric motor, including: a torque imparting device configured to impart, to an input shaft, a torque in a direction to retract a piston based on an elastic torque of a torsion spring and including a mechanism configured to allow a first retained portion provided at one end portion of the torsion spring to be retained by another one of a plurality of first retaining portions of a stator when the elastic torque exceeds a set upper-limit torque to decrease the elastic torque; and a mechanism configured to permit a second retained portion of a rotor to be retained by a second retaining portion provided at the other end portion of the spring to prohibit the elastic torque from becoming smaller than a set lower-limit torque.

According to some embodiments, a vibration-isolating system comprises a case, one or more environmental buffers, a platform suspended within the case by a plurality of wire rope isolators, a crumple zone beneath the platform and configured with one or more shock-absorbing structures, and a container assembly configured on the platform. The container assembly is operable to protect a payload comprising a flexible panel. The container assembly comprises a back panel positioned behind the flexible panel and offset by a first substantially airtight compartment, a front panel positioned in front of the flexible panel and offset by a second substantially airtight compartment, and a stiffener panel positioned in front of the front panel and offset by a third substantially airtight compartment.

A latching connector having a pin, a housing, and a canted coil spring is disclosed. The housing has an opening that slidably receives the pin. The housing and the pin each have a groove that is sized and dimensioned to receive a portion of the canted coil spring. The pin groove and housing groove have a curved surface with a radius that is equal to or larger than the major axis of the canted coil spring. The canted coil spring has an outer diameter that is equal to or larger than the diameter of the housing groove. Together, the pin, housing, and canted coil spring provide a latching connector with a reliable and consistent connect force and disconnect force. The latching connector provides improved electrical conductivity from the pin to the housing by providing multiple contact points with the canted coil spring.

According to certain embodiments, a vibration-isolating case comprises a resilient, plastic-composite walled case and vibration-damping footing located at the bottom side of the case. Each vibration-damping footing comprises a mounting plate, cushions, and a damping system. The mounting plate has a flat surface and side surfaces extending from the flat surface to form a channel-shaped structure. The flat surface is positioned proximate a bottom outer surface of the case and couples to at least one brace within the case. The cushions are positioned within the channel-shaped structure such that the side surfaces of the mounting plate protect at least a top portion of each cushion. The damping system is positioned between the cushions and comprises a tray containing a quantity of inelastic particulate. A mechanical path exists between the vibration-damping footing and a platform mounted within the case.

A pawl return spring includes a surface contacting portion adapted to contact a transmission housing. The surface contacting portion includes a first connection region and a second connection region opposite the first connection region. The pawl return spring includes an active coil region connected to the first connection region and disposed about a central longitudinal axis to provide torsional effort to the system. The pawl return spring also includes an inactive coil region connected to the second connection region and disposed about the central longitudinal axis that does not provide torsional effort to the system.

A coil spring for use in a cavity, such as in a groove of a pin, a housing, or both. The cavity can also be part of a seal assembly. The coil spring can have a longitudinal component positioned within the plurality of interconnected coils that runs along the spring coil axis in order to increase rigidity of the coil spring. The longitudinal component applies a load against the coil spring and/or provides restriction against the coil spring taking a shape or size different than that of the coil spring retaining groove.

According to certain embodiments, a container assembly for protecting a flexible panel comprises a back panel positioned behind the flexible panel and offset by a first substantially airtight compartment, a front panel positioned in front of the flexible panel and offset by a second substantially airtight compartment, and a stiffener panel positioned in front of the front panel and offset by a third substantially airtight compartment. The front, back, and stiffener panels each comprise one or more rigid materials. Each rigid material has higher natural frequency and lower excursion properties than the flexible panel. The container assembly is tuned using fixed, gas-piston principles to impart the higher natural frequency and lower excursion properties of the rigid materials to the flexible panel such that the natural frequency of the flexible panel increases and the extent to which the flexible panel experiences excursions greater than 350 microns is reduced.
