  • Patent number: 7211069
    Abstract: A needle cover for covering an injection needle of an injection device, such as an injection pen, including a cover which can be shifted longitudinally along the longitudinal axis of the needle and which covers a proximal end of the needle in a needle protecting position, a restoring means for axially returning the cover from a retracted position towards the proximal end of the needle into an advanced position, and a latch for preventing the cover from being retracted in the needle protecting position, wherein the position of the cover is different in the advanced position and in the needle protecting position, and the latch is activated to prevent the cover from being retracted when the cover is shifted near to the needle protecting position. The present invention encompasses a cannula support comprising such a needle cover, wherein the needle cover is detachably or non-detachably connected to the cannula support.

  • Publication number: 20060290187
    Abstract: A fitting for a vehicle seat, in particular for a motor vehicle seat, has a first fitting part (11), a second fitting part (12) in geared connection with the first fitting part (11), and an eccentric (26, 27) for driving a rolling movement of the second fitting part (12) on the first fitting part (11). The eccentric is defined by at least one driving ring (26) and two wedge segments (27). The wedge segments (27) are braced with respect to one another. The driving ring (26) encloses the wedge segments (27). For each of the wedge segments (27), the outer side of the wedge segment bears along at least one outer supporting line (33) against the driving ring (26).

  • Patent number: 7120820
    Abstract: A redundant control system having at least a first and a second control computer (1,2) and at least one peripheral unit (5) that is connected to the control computers (1,2) by a bus system (3,4). Both control computers transmit cyclically changing signs of life (LzX, LzY) to the peripheral unit (5), which checks whether a change in the signs life has taken place within a given time period and which switches to the other control computer for executing the control tasks if the change in the sign of life is not timely received.

  • Publication number: 20050271465
    Abstract: A device comprising an outer part and an inner part accommodated in the outer part wherein longitudinal grooves are provided within the inner part so as to receive longitudinal ribs of an injection needle. Protrusions that are disposed on the outer part and recesses which are arranged within the inner part allow the inner part to be twisted only in one direction relative to the outer part while putting up resistance to said twisting movement. A spring tenses the outer part and the inner part counter to each other in an axial direction.

  • Patent number: 5871414
    Abstract: Adjusting and fixing device for seats, like automobile seats, in particular for the adjustment of the back rest. For the adjustment of the back rest vis-a-vis the seat part a fixed mounting is arranged at the seat part. This fixed mounting is joined with an adjustable mounting for the back rest transferring the adjusting movement over a gearing drivable by means of a cam section, defining the position of these mountings related to each other. The gearing includes a radial tooth wheel belonging to a mounting and an internal gear rim of the other mounting catching into the first one, whereby counter toothings are arranged at the mountings. The cam section is formed by two wedge segments inclined against each other and encompassing the bearing point of the adjustable mounting regionally.
