  • Patent number: 9581147
    Abstract: The invention is an actuator which includes at least one control element which has thermally activatable transducer material and which, in response to the supply or dissipation of energy, changes from a first shape state into a second shape state, and a mechanical energy storage, which is functionally connected to the control element. When the control element is in the second shape state, it exerts a restoring force on the control element which returns the control element to the first shape state. The mechanical energy storage includes an elastomer body, which at least in some regions is in direct physical and thermal contact with the control element. The elastomer body is connected in a spatially fixed manner to the control element in at least two spatially separated joining regions along the control element.

  • Patent number: 8312977
    Abstract: An apparatus is disclosed for producing a frictional and/or form-fitting connection between first and second components which are linearly or rotationally movable relative to one another for transmitting forces and/or force moments that act between the first and second components in a linear and/or rotational manner. The first component surrounds the second component, at least sectionally, with at least one inner wall that faces the second component. The second component features at least one active-face element that can be transferred in a force-loaded manner from a first position, in which the active-face element is spaced apart from the inner wall, into a second position, in which the active-face element produces the frictional and/or form-fitting connection with the inner wall.

  • Publication number: 20120138407
    Abstract: A torque-limited coupling element is described, comprising an input part and an output part, each mounted rotatably about a common rotational axis, and at least one connecting means. If a predeterminable limit torque acting between the input part and output part is exceeded, the connection means can be transferred from a first position, in which the connecting means non-rotatably connects the input part and output part to one another forming a positive engagement, into a second position, in which the input part and output part are mounted rotatably relative to one another. Furthermore, a method for torque-limited coupling and uses for such a coupling element are described.

  • Patent number: 8061763
    Abstract: The invention relates to a device for a motor vehicle for protecting vehicle occupants when there is an impact of energy directed laterally at a motor vehicle door due to a collision, having a connecting structure which has at least two parts with a first part permanently connected with the motor vehicle door and a second part permanently connected with an energy-absorbing region of the motor vehicle body located in the vehicle interior. Both parts via at least one common joint region can be operationally connected with each other to conducting-away of at least part of the energy input laterally acting on the motor vehicle door in the region of the motor vehicle body. The energy impact acting on the motor vehicle door is conducted away from the pivot bearing by a force acting linearly and horizontally via the first and the second part to the first end of the second part permanently connected with the motor vehicle body.
