Safety devices for motor vehicles

Technical field

The technical solution relates to a safety device for motor vehicles.

BACKGROUND OF THE INVENTION

A hitherto known solution of the kind considered is an auxiliary device for locking the steering lever of motor vehicles, which comprises in the housing a pivotally arranged pawl operated from the lock cylinder by means of a slider, in which the lock cylinder is mounted from the other side of the cut-out pivotable into the cut-out by a part provided with a shaped contact surface for contact with the control lever, the lock cylinder being kinematically connected to the pawl by means of a slider. The lock cylinder is kinematically connected to the slider by means of a crank whose pin engages in a guide on the slider. The slider is equipped with a support surface for the latch and for kinematic connection with the latch nose. The latch is spring loaded. The attachment is located next to the control lever head and the lock cylinder housing extends through an opening in the control arm cover.

The disadvantage of this solution is that it consists of a large number of parts that occupy too much construction space.

The essence of the technical solution

SUMMARY OF THE INVENTION The object of the invention is to overcome the aforementioned technical drawbacks by a motor vehicle security device having a locking segment according to the invention, which essentially consists in that the locking segment is rotatably mounted on a bracket and coupled with a gearing.

From a functional point of view, it appears advantageous if the locking segment is shaped and when the locking insert is provided with a toothed segment.

For motor vehicles with manual transmission, it appears advantageous if the toothed segment of the lock cylinder is coupled with recesses on an auxiliary slider slidably mounted on a bracket, which by its shaped end is movably coupled with a recess on the locking segment.

• n

For motor vehicles with automatic transmission, it appears advantageous if the toothed segment of the lock cylinder is coupled with the toothing formed on the locking segment.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS The technical solution will be explained in more detail using the drawings in which FIG. 1 shows a safety device for motor vehicles with a manual transmission in the unlocked state, FIG. 2 shows a side view from the inside of the locking device according to FIG. 1, FIG. 3 shows the security device of FIG. 1 in the locked state, FIG. 4 shows a safety device for motor vehicles with an automatic transmission in the unlocked state, FIG. 5 shows the security device of FIG. 4 in the locked state.

Description of an exemplary embodiment

The security device of FIG. 1 consists of a locking segment 5 rotatably mounted by means of a pin 6 on a bracket i mounted in an unknown motor vehicle tunnel and provided with a cover 12. The locking segment 5 is shaped and is provided with a cutout 51 for a motor control lever 7 and a cutout 52 and 4. The auxiliary slider 4 provided with recesses 41 and a shaped end 42 for the locking segment 5 is slidably mounted in the bracket i between the wall st1 of the bracket 1 and the locking segment 5. On the outside of the wall 11 of the bracket I is locked 2, preferably rotatable, a portion 21 extending into the interior of the bracket 1 of FIG. 2, a toothed segment 3 is fastened, whose teeth 31 engage recesses 41 of the auxiliary slider 4. In FIG. 1, the locking device is in the unlocked state where the control lever 7 is freely movable.

When the control lever 7 is locked, rotation of the lock insert 2 reverses the toothed segment 3, whose teeth 31 engaging the recesses 41 of the auxiliary slider 4 move the auxiliary slider 4 within the bracket and roll by sliding movement in the cutout 52 of the locking segment 5 to its extreme position. of the locking segment 5, in which the beak 53 of the locking segment 5 fits into the shaped end 42 of the auxiliary slider 4 and the cutout 51 of the locking segment 5 secures the control lever 7 according to FIG. 3. When unlocking, the movement is reversed.

In an alternative embodiment, the locking device for the automatic transmission 5 of FIG. 4 and 5 consists of a locking segment 5 rotatably mounted by means of a pin 6 on a bracket i mounted in a motor vehicle tunnel (not shown) and provided with a cover 12. The locking segment 5 is shaped and is provided with a cutout 51 for the motor control lever 7 and toothed 54 in part. On the outside of the wall 11 of the bracket 1, a lock insert 2, preferably rotatable, is attached, on whose lower part 21 extending into the interior space of the bracket 1 is a toothed segment 3 whose teeth 31 engage with the teeth 54 of the locking segment 5. 4, the locking device is in the unlocked state where the control lever 7 is freely movable.

When the control lever 7 is locked, rotation of the lock insert 2 reverses the toothed segment 3 whose teeth 3i engage with the teeth 54 of the locking segment 5 and thereby rotates the locking segment 5, which locks the control lever 7 according to FIG. 5 in the locked position. When unlocking, the movement is reversed.

Industrial usability

The safety device for motor vehicles can be used in motor vehicles with manual and automatic transmission.
