Description

The invention relates to a device for releasable Connection of the hood of a motor vehicle to the motor vehicle chassis at the axis opposite the hood pivot Hood side, a hook pivotably mounted on the hood engaging a holding piece on the chassis.

In standard vehicles with a front engine, it is It has become common to connect the bonnet to the front of the vehicle chassis so that it can pivot, so that the The hood can be swiveled forward to expose the engine can. It has already been proposed to attach the hood to the Back via a screw-operated device with the Connect chassis.

The object of the invention is to provide an improved device of the type indicated at the beginning · This is achieved according to the invention in that the hook can be fastened to the hood in two aligned guide slots Housing rotatable and vertically displaceable is, wherein the hook is vertically movable into and out of engagement with the holding piece via an actuating lever and is guided in the housing in such a way that the hook from the holding piece after the Loelaeeen swings away

109811/1389

The hook is preferably arranged with the end facing away from the holding piece between the ends of two vertical, parallel straps and thus pivotably connected by a pin which also penetrates the guide slots in parallel side walls of the housing, the straps at the other end being connected to one another by a further pin which passes through a guide slot of a quarter-circle-shaped swivel plate, which can be swiveled by means of the actuating lever in the housing about an axis lying on a straight line with the pins of the tabs. ψ. The swivel plate can advantageously be attached to a spindle which is mounted in bearings in the walls of the housing, passes through aligned slots of the tabs and protrudes from the housing with one end for attaching the actuating lever.

In a further advantageous embodiment of the invention, the hook is adjustable in length. The hook can consist of one with the Haitestück cooperating part and from one exist rotatably and vertically displaceably connected to the housing part, which has a screw bolt, on which the other part is fixed axially adjustable.

The hook preferably has a rabbit, which is used to pivot the hook away from the holding piece after it has been released the same engages with the movement of the hook on the holding piece along on a Bolle in the housing.

Finally, a pivotably mounted safety shake can be provided with a second holding piece cooperates and is arranged such that it can not be moved away from it while the main hook is in the fixing position is located.

Below are two embodiments of the invention For example, described with reference to the accompanying drawings. Show in it:

Pig, Fig. 1 is a front view of a device according to the invention in the plague position

Fig. 2 shows the side view of the device according to Pig. 1}

ilg. 3 those of the pig. 1 corresponding front view of a second embodiment of the advantages of the present invention similar direction.

Pig's device. 1 and 2 has a hook formed from two flat, complementary forgings 10, which are firmly connected to one another, for example by riveting or welding. The top of the Hook 10 is between the lower ends of two vertical, parallel and identical tabs 11, 12 thus arranged the hook 10 is pivotably connected by a pin 13. The ends of the pin 13 penetrate one another aligned vertical guide slots 14 in parallel, profiled walls of the housing 15 and is guided therein. That Housing 15 is firmly connected to the frame of an engine hood the.

The upper ends of the tabs 11 and 12 are connected by a pin 16 provided with radial shoulders and kept at a distance from each other, which has an arcuate guide slot 1? in an approximately quarter-circle Pivot plate 18 passes through, which is arranged between the tabs 11 and 12. The pivot plate 18 is welded to a spindle 19, which is pivotably mounted in bearings in the walls of the housing 15 and aligned with each other lower

right seat braid 21 in the tabs 11 and 12 penetrated. the Spindle 19 and pins 13 and 16 are aligned vertically with one another, i.e. lie on the same vertical straight line. One end of the spindle 19 is designed as a square 22 on the an operating lever 23 can be attached.

One end of the guide slot 17 is further away from the spindle 19 than the other, so that when a The plate 18 is pivoted by the lever 23 of the hook 10 rises and falls.

In Fig. 1, the hook 10 is shown in its highest position, in which it is after hanging in a rod-shaped Retaining piece 24 on the motor vehicle eugchas sis has been moved to pull the hood tightly down against the chassis.

The hook 10 is loaded by a spring 25, which a flat, vertical edge on the rear side of the hook 10 presses into contact with a guide roller 26 on the housing 15. If the hook 10 rests on the roller 26, then it assumes such a position that when the hood is moved down a rounded edge 27 forming a nose at the lower end of the hook 10 meets the holding piece 2A- so that the hook 10 pivoted to the side and runs past the holding piece 24, whereupon the spring 25 him in the reproduced in Fig. 1 full engagement osition withdraws.

A further hollow 28 is provided on the housing 15, and is arranged in such a way that when the hook 10 descends by actuating the lever 23 to disengage the hook 10 with the holding piece 24, a nose 29 on the hook 10 strikes the roller 28 and the hook 10 swings counterclockwise about its pivot axis, so that the

The hook 10 does not come into contact with the retaining piece 24 when the bonnet is folded up.

A guide plate 31 can be attached to the housing 15 be, which is on one side of the hook 10 down extends and has a wide hat 32 at the bottom edge, which has rounded inlet edges and the holding piece 24 picks up when the hood is lowered.

The embodiment according to Mg · 3 differs thereby from the one after Pig. 1 and 2 that a hook with adjustable effective length is available. Same parts the two embodiments are provided with the same reference numerals.

In the embodiment according to Pig * 3, the hook points a lower part, designed as a forged piece, provided with a sleeve section 33 and a hook section 34- cooperating with the holding piece on · through the bore of the sleeve section 33 runs a screw bolt 35 »on the the sleeve section 33 is fixed in the desired position by means of nuts 36 and 37. The screw bolt 35 is with its upper end in a threaded hole of a second part 38 designed as a forging is screwed in. This part 38 can be pivoted on a pin 39 of the tabs 11, 12 stored, which the pin 13 according to the embodiment Pig. 1 and 2 corresponds to

A safety hook (not shown) can also be provided. This safety hook can be provided on the housing 15 and with a separate holding piece cooperate on the motor vehicle chassis, being spring-loaded in such a way that it engages the associated holding piece, when the main hook is not in the locked position and the bonnet begins to open. A nose at the upper end of the safety hook can extend over the pivot pin 13 of the main hook to prevent the Safety hook is moved to the open position when the main hook is in the locked position. After loosening of the main hook, the safety hook can then be moved into the open position, either by direct Manual actuation of the hook itself or by remote actuation by means of, for example, a Bowden cable.
