  • Patent number: 11577571
    Abstract: A clamping plate is dimensioned to secure a flexible spring member to an end member for forming a gas spring assembly. The clamping plate includes a clamping plate wall with an axis and opposing surface portions oriented transverse to the axis. An opening extends into the clamping plate wall from along each of the opposing surface portions. An elongated damping passage extends in a spiral configuration through the clamping plate wall in fluid communication with the openings. A gas spring assembly includes a flexible spring member that defines a spring chamber, and an end member with an end member wall that defines an end member chamber. The clamping plate is secured to the end member and retains the flexible spring member thereon. The elongated damping passage is in fluid communication between the spring chamber and the end member chamber. Gas transfer between the spring chamber and the end member chamber generates pressurized gas damping during use of the gas spring assembly.

  • Patent number: 11204076
    Abstract: An inertia-actuated valve assembly includes a valve housing, a valve body and a biasing element. The valve housing includes a groove that has an open end fluidically accessible from along one side thereof. The valve housing includes a flow channel extending therethrough in fluid communication with the groove from along an opposing side of the valve housing. The valve body is positioned within the groove of the valve housing such that the valve body and the valve housing are axially co-extensive along at least a portion thereof. The biasing element operatively engages the valve body and generates a biasing force urging the valve body in a first axial direction. The biasing force is greater than a predetermined dynamic gas pressure threshold value multiplied by a pressure area and is less than or approximately equal to a valve body mass multiplied by 2.5 times the nominal acceleration due to gravity.

  • Patent number: 11148579
    Abstract: An air scoop light unit for a vehicle includes a light emitting area and related features where the light unit comprises a concave guiding surface spaced apart from the vehicle body to form an airflow channel there between that guides airflow at least partially around an outer side corner of the vehicle body to enhance aerodynamic efficiency. The air scoop light unit may incorporate safety features such as sensing devices as well as features that allow the air scoop light unit to deform, break or move in a predetermined manner such as to absorb energy in case of contact with an object such as a pedestrian. Vehicles including one or more such lamp assemblies are also included, including vehicles having tapered bodies.

  • Patent number: 10830307
    Abstract: Vibration isolators can be dimensioned for securement between a rotational motion source and a rotational motion target. The vibration isolators can include a first end member and a second end member supported in substantially-fixed axial position but axially-rotatable relative to the first end member. An intermediate member can be disposed between and operatively engaging the first and second end members. A rotational motion-to-axial motion conversion system is operatively disposed between the intermediate member and the first end member such that rotation of the intermediate member and the second end member generates axial displacement of the intermediate member relative to the first and second end members. A biasing element can be operatively disposed between the intermediate member and one or more of the first and second end members to bias the intermediate member in an axial direction. Rotary power transmissions or system are also included.
