Definitions

• the invention relates to a motor vehicle door arrester consisting of a first part which can be attached to a door arrangement part, door or door spar and a second part which can be attached to the other door arrangement part, at least one braking and holding body loaded by at least one spring being arranged between the two parts, and one of the the two parts are formed by an element which is movable relative to the other part and which is arranged in a correspondingly distributed manner with the intended holding positions of the door and which cooperates with the spring-loaded braking and holding bodies.
• Such motor vehicle door arrestors are known in a large number of designs, and in the course of time two main designs have emerged, one of which has a holder housing which is penetrated by a holder housing containing a spring-loaded braking and holding body and which has thickened portions or the like and is provided with braking ramps or locking marks and the like the other of which is characterized by recess segments or projections which have latching marks and a torsion bar spring which forms the braking or holding body directly or indirectly.
• An increased surface roughness of surfaces that are movable relative to one another in the first place necessarily leads to a noise development when the two parts move relative to one another.
• an increased surface roughness of two parts that are movable relative to one another also results in an increase in the force required to initiate the relative movement of the two parts with respect to one another, with the result that a relative movement takes place only after a certain, essentially from the progress of increasing the surface roughness, dependent force increase.
• this phenomenon leads to a sudden onset of the relative movement between the spring and the brake and holding body after exhaustion of an adjustment path of the braking and holding body which is intended as a braking path and thus to a highly unpleasant and, accordingly, highly undesirable noise development in the door stay.
• the invention is therefore based on the object of further developing a motor vehicle door lock of the type mentioned in such a way that, while maintaining its basic design features, on the one hand the effort associated with the use of bearing shells or bearing bushes or the use of coatings from a maintenance-free bearing material is avoided , on the other hand, at the same time, the disadvantages resulting from an increase in the roughness of the surfaces interacting in a sliding manner with increasing operating time, above all of the load spring and holding body, are eliminated.
• this object is essentially achieved in that the spring which interacts with a braking and holding body is surface-hardened at least in the region of its contact with the braking and holding body.
• the measure according to the invention can also be used to prevent surface areas of the load spring, which are in frictional contact with one another, and their support from being prevented from forming increasing surface roughness.
• the invention basically consists in the simplicity of the measure for preventing surface wear of the interacting surface areas of the load spring and the braking and holding body, its principal application is not exclusively for use in the area in contact with the braking and holding body Load spring limited.
• Another general aspect of the measure according to the invention is that it can in principle also be used for any type of door dividers based on the interaction of braking and holding bodies with a door holding rod provided with braking and holding ramps.
• the spring cooperating with a braking and holding body is surface-hardened both to the area of its contact with the braking and holding body and to the area of its contact with a mounting or clamping device.
• a typical torsion bar spring door lock structurally combined with a door hinge, it can initially be provided that the first part struck on one door arrangement part by a detent segment containing the detent marks and the second part struck on the other door arrangement part by a torsion bar spring and the brake and holding body is formed by a roller mounted on the free load arm of the torsion bar and that the load arm of the torsion bar is surface hardened over its length section forming the roller bearing.
• the torsion bar spring has an S-shaped or C-shaped shape and is held via its shaft part in a groove-like recess in the hinge leaf of the one hinge wing and via its support arm is supported against the hinge leaf of one hinge wing and is equipped in the end region of its free loading arm with a bearing for the roller forming the brake and holding body.
• a torsion bar spring equipped with an S-shaped or C-shaped torsion bar spring and structurally combined with a door hinge Door lock also be provided that the shaft part of the S-shaped or C-shaped torsion bar spring held over a part of its length in a groove-like recess in the hinge leaf of the one hinge wing via the length section in engagement with the groove-like recess at least over that area its circumference, over which it is in engagement with the groove-like recess in the hinge leaf, is surface-hardened.
• the free load arm of the S-shaped or C-shaped torsion bar spring held in its hinge leaf by way of its shaft part in a groove-like recess in a hinge leaf forms a longitudinal section of its end area towards the braking and holding body and is equipped in this area with a surface hardening over part of its circumference.
• Figure 1 is a schematic representation of a torsion bar door lock structurally combined with a door hinge
• Figure 2 is a side view of an S-shaped torsion bar spring.
• the torsion bar door lock shown in the drawing structurally combined with a door hinge, in particular for detachable motor vehicle doors, consists of a hinge with two hinge wings 2 and 3 pivotally connected to one another by means of a hinge pin 1, one of which 2 remains on the door body (not shown in the drawing) and the other 3 of which can be detachably fastened to the door pillar (also not shown in the drawing) and a torsion bar door lock 4.
• the hinge wing 3 which can be releasably fastened to the door pillar in the exemplary embodiment shown is formed from a U-shaped sheet metal blank, with the upper, transverse to the hinge axis directed leg 5 of the U-shape alternately successive projections 6 and recesses 7 formed locking segment 8 of the door retainer 4 is formed and on the lower, transverse to the hinge axis leg 9 of the U-shape a parallel and in the same direction to a hinge height extending extension 10 of the hinge pin 1 directed pin-shaped projection.
• the hinge wing 2 has an approximately L-shaped cross-sectional shape and is arranged to engage in the hinge wing 3, whereby it is rotatably connected to the hinge wing 3 by means of its one profile leg via the hinge pin 1 and is fastened to the door via its other profile leg 13.
• the torsion bar door arrester 4 structurally connected to the hinge in the embodiment shown has an S-shaped torsion bar spring, which is mounted above its sheep part 14 in a groove recess 19 in the hinge leaf of the engaging hinge leaf 2 and is supported against it via a support arm 16, the load arm 17 of which forming area overhangs the two hinge wings 2 and 3.
• the loading arm 17 of the torsion bar spring interacts with the detent segment 8 of the door arrester 4, which is formed on one leg 5 of the U-shape of the hinge wing 3 and consists of projections 6 and depressions 7 arranged alternately in succession and, in the embodiment shown, has three detent positions for the door 4 .
• S-shaped torsion bar spring which is mounted above its sheep part 14 in a groove recess 19 in the hinge leaf of the engaging hinge leaf 2 and is supported against it via a support arm 16, the load arm 17 of which forming area overhangs the two hinge wings 2 and 3.
• the loading arm 17 of the torsion bar spring interacts with the detent segment
• the load arm 17 of the torsion bar spring has a surface hardening 18 over its length section which interacts with the catch segment 8.
• the shaft part 14 of the torsion bar spring can also be provided with a surface hardening 20 extending over part of its circumference by way of its length section lying in a groove recess 19 of the hinge leaf 2 when the door retainer is mounted.
