  • Publication number: 20240076058
    Abstract: A system for determining the number of passengers in a vehicle, comprising a plurality of sensors arranged to collect data concerning a cabin of the vehicle, wherein the plurality of sensors comprises at least one mm-wave-radar-sensor, and a computation unit, wherein the computation unit is connected to the plurality of sensors and configured to evaluate the data collected by the plurality of sensors in order to determine the number of passengers within the vehicle. Also provided is the vehicle with the system and a method for determining the number of passengers in the vehicle.

  • Patent number: 10400845
    Abstract: A seal guide unit for guiding and sealing a piston rod of a vibration damper having a first guide element and a second guide element fixedly connected to the first guide element and arranged coaxial to the first guide element, and a radially moveable piston rod seal arrangement arranged coaxially between the two guide elements and is at least indirectly surrounded in circumferential direction by at least one guide element, including a defined radial annular gap, and comes in at least indirect axial contact with at least one guide element. The piston rod seal arrangement includes a piston rod seal and a sliding element which encloses the piston rod seal in circumferential direction and axially limits the piston rod seal at least on one side. The sliding element has a lower friction coefficient than parts of the seal guide unit adjoin the piston rod seal arrangement.

  • Patent number: 9261159
    Abstract: A piston-cylinder unit for a mono-tube damper, includes: a cylinder having an inner wall and a closure fixed axially with respect to the cylinder by positive engagement with one or more impressions of the inner wall, the closure having a plug sealed with respect to the inner wall, the plug having a reinforced portion and being axially moveable with respect to the cylinder when a temperature threshold is exceeded. Axial movement caused by the temperature threshold being exceeded causes deformation of the plug with respect to the cylinder so as to: (i) form a channel between the plug and the inner wall of the cylinder, through which pressure, caused by the increased temperature, can escape the piston-cylinder unit, and (ii) permit axial movement of the closure only to a point at which the reinforced portion of the plug comes into contact with the one or more impressions in the cylinder.
