Abstract: A device for mixing the components of a mass flow flowing through it, provides a particularly homogeneous mixture with any desired long-term stability, even if components which are generally immiscible or can only be mixed with very great difficulty are being mixed. The device has a body (8), which it is difficult for medium to flow around, arranged in a through-flow chamber (4), this body being arranged at least partially in a part of the through-flow chamber (4) which widens in the direction of flow, so that the cavitation action and mixing action of the supercavitation field generated by the body (8) which it is difficult for medium to flow around is significantly reinforced.

Abstract: In a longitudinal adjuster for a vehicle seat having a freely pivotable backrest, with the longitudinal adjuster having a first seat rail, a second seat rail, in relation to which the first seat rail can be slid in the longitudinal direction, and a memory device (11) which is assigned to the first seat rail, interacts with the second seat rail and stores a longitudinal seat position which can be left by means of a longitudinal displacement of the vehicle seat when the backrest pivots freely, and resumed when the backrest pivots back, a displacement measuring device (21), which can be operatively connected to the second seat rail, and a control signal generator (53), which can move in relation to the displacement measuring device (21), are provided for playing a role in resuming the stored longitudinal seat position.

Abstract: The present invention pertains to a longitudinal adjustment device for vehicle seats, in which the seat is attached along each of its long sides to runner rails 10, mounted with freedom to slide in guide rails 15, which are attached to the vehicle. Each runner rail 10 has a locking device, which can be released from its connection to the guide rail 15. The locking device comprises a release lever 21, 22, supported with freedom to swivel on each runner rail 10, to move the device into its released position, which lever is to be shifted via rods 31, 32 of an actuating element 30 supported on the runner rails 10. The adjusting moment exerted on the actuating element 30 is transmitted to the rods 31, 32 via a differential, where the rods 31, 32 are disconnected from each other. As a result, each rod can be moved until the locking device has been moved completely into the position in which it is released.

Abstract: A manual lever drive for an adjusting device on a seat for converting a lifting movement into a discontinuous rotational movement has a support arm and a step-by step mechanism having an output member and an input member. The output member is configured to be coupled with a rotatingly moveable control member of the adjusting device. A transmission member is connected to the input member for torque transmission onto the input member. A manual lever is connected to the support arm so as to pivot about a first axis of rotation. The manual lever is configured to actuate the transmission member. The transmission member is arranged on the input member providing a second axis of rotation. A pivot angle of the manual lever imparts to the transmission member a pivot movement increasing a corresponding pivot angle of the second axis of rotation.

Abstract: A device for mixing the components of a mass flow flowing through the same provides a particularly homogenous mixture which remains stable for any length of time, even when the components concerned are generally not miscible or are very difficult to mix. The device has a body (8) which is located in a throughflow chamber (4) and is difficult to flow around. This body is situated at least partially in a part of the throughflow chamber (4) that expands in the direction of the flow, so that the cavitation effect and the mixing effect of the supercavitation field produced by the body (8) that is hard to flow around are considerably amplified.

Abstract: In a vehicle seat, in particular a motor vehicle seat, having a seat substructure (3) and a backrest (6) which is to be fastened to the seat substructure (3), the backrest (6) can be fastened to the seat substructure (3) by means of a quick-fitting connection (10, 13).

Abstract: A stop element for limiting the regulating distance of a longitudinal adjustment device for motor vehicles seats, whose seat part is fastened on sliding rails, wherein each sliding rail is longitudinally slidable in a guide rail secured on the vehicle floor and at least one sliding rail can be secured on the guide rail in selectable longitudinal positions by means of a locking device, is provided between the sliding rail and the guide rail. The stop element is formed of an impact member, having a snap-in head penetrating a penetration of the guide rail, and a locking hook, penetrating this impact member and lockingly engaging the guide rail.

Abstract: A longitudinal adjusting device on a motor vehicle seat having a seat back adjustable relative to the seat part and forwardly foldable after releasing an arresting device, has movable rails on which the seat is fastened. The moveable rails can slide in guide rails attached to the vehicle. One movable rail has a locking device that releasably locks the moveable rail on the guide rail. The locking device has a positioning device for returning the seat to its previous longitudinal position. The positioning device has a positioning disc with locking teeth and an arresting lever with a toothed segment engaging the locking teeth. The arresting lever can be released from the locking teeth to allow rotation of the positioning disc during longitudinal adjustment of the seat. A spring-loaded winding drum is arranged coaxially to the positioning disc and allows the seat part to slide forward by a tension member attached to the seat part or the guide rail.
