摘要:
A head restraint for a vehicle, which in its stowage position is received by a hollow in the rear window shelf of the vehicle and which can be transferred, together with its bearing arms, into an operational position near to the backrest, the bearing arms being supported on the vehicle side on an inside wall of the hollow, so that, in the stowage position, both the head restraint and its bearing arms rest in the hollow. Before, during or after a swinging operation, the head restraint is pivoted in the opposite direction to the swing of the bearing arms, so that employment in a confined space is possible.

A motor vehicle provided with a hatch-back door closing off a storage space, in which two blinds arranged in a common housing are provided whose axes of rotation extend in the transverse direction. The blind serving the separation of the passenger space from the storage space is adapted to be suspended in its pulled-out position within the roof area, while the free end of the blind serving to cover the stored items is fastened within the area of the hatch-back door.
摘要:
A surface heater body which is constructed as two-layer, expanded partial composite laminated body and contains two mutually separated channels or channel systems adjoining one another wall-to-wall in a heat-conducting manner; one channel system which extends over the entire area of the surface heater body and which is hermetically closed off, operates as heat-pipe to distribute the supplied heat over a large area; a heat channel traversed by heating water extends along the bottom edge of the surface heater body; a rectilinear continuous non-expanded strip is provided between the heat channel and the heat-pipe channel system, along which the partial composite laminated body is bent U-shaped so that the heat channel and the heat-pipe channel system come into mutual abutment where they are permanently and heat-conductingly connected with each other over the entire contact surface; a separate pipe may also be provided as heat channel or, as a still further alternative, a heat-pipe may be inserted into the heat-pipe channel system whereby the two edges of the surface heater body are sealed off at the places where the heat pipe leaves the heater element.
摘要:
A heat-exchanger with a bundle of parallelly extending pipes adapted to be acted upon by air which are constructed in the manner of heat pipes; a connection box extends transversely to the pipe bundle which surrounds section-wise the heat pipe hollow spaces of the pipe bundle and which is adapted to be traversed by a heat carrier medium; the connection box essentially consists of an extruded profile whose profile direction is disposed parallel to the pipe rows of the bundle and is provided at its end faces with guide covers which take over the distribution and deflection of the heat carrier medium toward the channels inside of the extruded profile.
摘要:
A heat-exchanger with a bundle of parallelly extending metallic pipes arranged at least in one row which are hermetically closed off and constructed in the manner of heat pipes, and with at least one metallic heat-exchanger head extending transversely to the pipe bundle which is sealed off from a flow point of view with respect to the pipe hollow spaces of the pipe bundle but is in heat-transferring connection therewith; the heat-exchanger head is thereby formed of at least one three-layered flat partial composite laminated body per pipe row which includes two separate channels or channel networks, and which is directed parallel to the associated pipe row; one of the channels of a partial composite laminated body is thereby connected with the heat pipe hollow spaces of the pipe row to form a heat pipe channel while the other channel is adapted to be acted upon by the heat carrier medium and forms a heat carrier channel.
摘要:
A surface heat-exchanger body for vehicles, aircrafts or ships, with an interconnected heat pipe-channel system which is hermetically closed and arranged distributed over an area; as a result of a separate line-shaped heat source which extends along the heat-exchanger body and which may be formed by a heating channel, a heating rod or the like, heat is supplied to the heat-exchanger body which is distributed and given off by the heat pipe-channel system to the adjoining space with a slight temperature drop inside of the heat-exchanger body; for a horizontal installation of the heat-exchanger body, intersecting or star-shaped channel sections are provided inside of the heat pipe-channel system which always return the condensate to the condensate collector independently of the direction of the resultant of gravity and inertia forces; the condensate collector may be constructed in the form of a closed annular line either concentrically on the inside of the surface heat-exchanger body or along the outer edge; to enhance the condensate return, the surface heat-exchanger body may be slightly arched, whereby the condensate collector must be placed at the geodetically lowest place.
摘要:
A heat-exchanger with a bundle of parallelly extending pipes adapted to be acted upon by air which are hermetically closed and constructed in the manner of heat-pipes. A heat-exchanger head which is adapted to be traversed by a heat carrier medium extends transversely to the pipe bundle. The heat carrier channels formed therein are sealed off from a flow point of view against the heat-pipe hollow spaces but are in good heat-transferring connection therewith. The heat-exchanger is formed by two types of heat-exchanger plates of which the first type extends over the air stream and the heat-exchanger head and of which the second type of heat-exchanger plates is limited to the heat-exchanger head and extends transversely to the first type of heat-exchanger plates and is brazed thereto over a large surface. The heat-exchanger plates can be constructed as extrusion profiles or as two-layer partial composite laminated bodies; extrusion profiles may also be used for the cross connection of the individual heat-exchanger plates of the same type, which are grooved transversely and are brazed to the end faces of the heat-exchanger plates. However with partial composite laminated bodies, connecting pipes extending transversely to the heat-exchanger plates are preferable.
摘要:
A belt strap windup device for eliminating a belt slack of a safety belt system of a motor vehicle upon the motor vehicle exceeding a predetermined vehicle deceleration. The windup device includes a belt roll-up mechanism, a shaft which is constantly acted upon by a retractor, and a windup reel to which the belt is mounted. A pulley is coupled with the shaft at least upon the predetermined deceleration of the vehicle, and an electrically ignitible propellant charge is arranged centrally with respect to the shaft, with the charge being adapted to act upon a driving fluid after an ignition thereof so as to operate the pulley so as to eliminate the slack in the belt. A belt strap mounting recess is provided in an interior of the shaft with a longitudinally aligned belt passage slot and with an insert opening lying at the end face of the shaft. The shaft includes a number of annularly arranged axially aligned ducts filled with the driving fluid, with the ducts terminating at an end face of the shaft. The fluid in the ducts is adapted to be acted upon by the propellant charge after an ignition thereof.
摘要:
A wind-up mechanism for eliminating the belt looseness of a safety belt system when exceeding a predetermined deceleration, in which an ignitable propellant charge, provided for triggering the retraction movement of the belt is arranged centrally in the hollow shaft of a belt roller that blocks automatically in case of danger. A liquid medium is preferably disposed in front of the propellant charge which, after the ignition of the propellant charge, drives a rotor coupled at that instant with the wind-up roller so as to eliminate the belt looseness by the gases forming during the ignition of the propellant charge. The hollow shaft accommodates at one end a cap and a toothed rim connected therewith, into which engages a blocking mechanism triggered in case of danger, while at least a part of the rotor is formed-on at the other end of the shaft in the course of a cold-flow or casting operation.

A headrest for a motor vehicle in which an inflatable bellows forms the headrest which is provided with elastically yielding drawbands that return the bellows into its folded-together position when the bellows is deflated by withdrawing therefrom the pressure.
