Abstract:
A motor vehicle seat back structure comprising a backrest support frame which consists of a surface turned towards the seat user's back, a lordosis support which is arranged on the front part of the backrest support frame for supporting the user's back and an adjusting device for vertically adjusting the lordosis support position with respect to the extension plane of said backrest support frame. The adjusting device comprises at least one adjusting element operably connected to the lordosis support and at least one sliding element which is displaceable with respect to said adjusting element and interacts therewith in such a way that when the sliding element moves, the adjusting element is displaced with a directional component perpendicularly to the displacement direction of the sliding element and performs an action on said lordosis support in the direction.
Abstract:
A support with a lumbar adjuster device for a motor vehicle seat includes a front side which, in the installed position, faces a seat user's back and a lumbar adjuster device which is arranged on the front side of the support and is intended for setting the position of the lumbar support perpendicular to the plane of extent of the backrest frame. The lumbar adjuster device has at least one adjuster element to be brought into operative connection with the lumbar support, and at least one slide which is movable with respect to the adjuster element. The slide can be moved, firstly, along a tensioning direction along which it is pretensioned, and, secondly, along a drawing direction along which a drawing force can be transmitted to the slide via a drawing means coupled to the slide.
Abstract:
A manual adjustment of a back support on a vehicle seat includes comprising a cable pulley which is selectively rotatable in a drive direction or in a driven direction oriented counter to the drive direction, and a tensile device associated with the cable pulley, which may be rolled up onto the cable pulley by rotating the cable pulley in the drive direction. The tensile device is able to be coupled to a back support of a vehicle seat such that the rotation of the cable pulley in the drive direction and/or driven direction affects an adjustment of the back support. A pretensioning acts on the cable pulley—which produces a torque of the cable pulley in the driven direction.
Abstract:
An adjusting system of a motor vehicle for the adjustment of a closing part is disclosed. The system includesa first and second casing extending oblong in a length-wise direction. The second casing has a smaller cross section than the first casing and is arranged within the first casing to be adjustable in a length-wise direction. A spindle for the relative adjustment of a first casing to the second casing is included and arranged within either or both of the first and second casings.The system also includes an electromotor and a transmission connected with either or both of the spindle and second casing. In addition, at least one spring is arranged within either or both of the first and second casings and operates length-wise, such that one of the casings is attached on the side of the motor vehicle body and another of the casings is attached to the closing side.
Abstract:
A memory device, for a rail longitudinal guide for a motor vehicle seat, comprising two longitudinal guide rails displaceable towards each other, for the setting of the longitudinal seat position, a first memory module, which may be displaced along one of the two guide rails to set a memory position, a locking device for locking a set memory position, a second memory module, arranged on the second of the guide rails and a stop which, on reaching a relative position of the two guide rail corresponding to one of the memory positions, engages with a counter stop on the first memory module. The second memory module comprises a base body made from plastic, by which the latter is fixed to the second guide rail.
Abstract:
A drive for adjusting devices includes gear elements mounted in a gear housing which includes at least two plates that can be secured to each other by plug connectors. The connectors are also configured as supporting joints that absorb the forces of the gear elements. A method for assembling the gear housing includes prefitting the gear elements and the housing plates by fitting the housing plates together about the gear elements with plug connectors, holding the housing plates with a holding device with sufficiently light holding forces so that the housing plates can be aligned when the gear elements are turned, turning the gear elements for the purpose of aligning bearing points of the gear elements, and securing the position of the gear elements and the housing plates relative to each other by permanently fixing the position of the housing plates in all three-dimensional directions through action on the plug connectors.
Abstract:
An installation for controlling the charge-cycle of an internal combustion engine which includes an inlet valve and an exhaust valve as main control devices as well as a shutter arranged in the suction system as auxiliary control device. At low rotational speeds and at full load of the engine, the shutter is so controlled that it rapidly opens a cross section in the suction system during the end phase of a suction operation. An increased velocity of the fresh gas flow and a pressure wave prior to inlet-closure is achieved thereby which increases the cylinder fill. This high pressure level can be maintained in the suction system or in the manifold between the auxiliary control device and the main control device by premature closing of the auxiliary control device. A preferred embodiment includes a valve or flap symmetrically arranged on a rotating shaft which is drivingly connected with an electromagnetic rotary adjusting device that drives the valve or flap oscillatingly and/or rotatingly with very high angular accelerations and decelerations. A valve controlled according to a performance graph and driven by a motor may serve, in addition to an increase of the full load cylinder fill at low rotational speeds, also for the partial load control of the internal combustion engine.
