Description

BRIEF DESCRIPTION OF DRAWINGS

(1) The following are shown:

(2) FIG. 1 a lateral view on a motor vehicle in the area of a lateral door with a handle,

(3) FIG. 2 a cross-section along line II-II from FIG. 1 in the area of the handle and in an unoperated position,

(4) FIG. 3 a cross-section along line II-II from FIG. 1 in the area of the handle, whereby the handle is reproduced in a normal operation, and

(5) FIG. 4 a cross-section along line II-II from FIG. 1, whereby the handle is illustrated moved out of the guide.

(6) A lateral view of a motor vehicle 1 is shown in FIG. 1. A lateral door is illustrated with a lateral door panel 3 and a handle 4. The motor vehicle lateral door 2 is shown in the closed state and lies flush to a lateral wall 5 of the motor vehicle. The lateral door 2 is held in a closed position by means of a motor vehicle locking mechanism.

(7) In the area of the handle 4 the motor vehicle lateral door 2 has a recess 7 in the form of a depression in the motor vehicle lateral door 2 so that an operator can easily grip the handle 4. The actuating means 8 is reproduced as a dot-dashed line. The actuating means 8 is connected on one side to the handle 4 and in the area of the motor vehicle locking mechanism 6 with an actuating lever 9. The motor vehicle lock 6 customarily interacts by means of a locking mechanism which is not illustrated with a lock holder which is mounted on the lateral wall 5.

(8) A cross-section along line II-II from FIG. 1 is shown in FIG. 2. The handle 4, the motor vehicle lateral door 2 and the actuating means 8 connected to an extension 10 is illustrated. The extension 10 of the handle is accommodated and mounted in a guide 11. The handle is mounted in the bearing point 12 and accommodated in this exemplary embodiment in a mounting 13 of the motor vehicle lateral door 2.

(9) The guide 11 has a stop 14 which is formed as part of a depression in the guide 11 in this exemplary embodiment. The extension 10 of the handle 4 has an elevation 16 corresponding to the depression 15 so that the handle 4 can be guided in relation to the motor vehicle 1, at least in the direction of the y axis. According to the embodiment and quality of the guidance of the handle 4 one, two or more depressions 15 and corresponding elevations 16 can be arranged in the guide 11. The depressions 15 and elevations 16 are preferably symmetrically arranged on the circumference of the guide 11. A symmetrical arrangement offers the advantage that very accurate guidance of the handle 4 is enabled in the guide 11. Naturally, according to the invention, it is also conceivable that the elevation 16 can be formed on the guide 11 and the depression 15 on the handle 4. Combined arrangements of depressions 15 and elevations 16 in the guide 11 or the handle 4 are conceivable according to the invention.

DETAILED DESCRIPTION

(10) A cut along the line II-II from FIG. 1 is shown in FIG. 3. The position of the handle 4 in an actuating position is illustrated in which the handle 4 completes a stroke H1 by means of which a sensor can be operated, for example, whereby the sensor transmits an electrical signal to the motor vehicle 6 in order to unlock the locking mechanism or the motor vehicle lock 6. The stroke H1 can be a stroke of 2-3 mm, for example. The stroke H1 is attained on the handle 4 by a small force F1 as a tensile force F1. After a stroke H1 the extension 10 and in particular the elevation 16 on the extension 10 reaches against the stop 14 of the guide 11. The stroke H1 produced by pulling on the handle 4 can consequently be limited by the interplay of guide 11 and extension 10 on the handle 4.

(11) FIG. 3 shows an exemplary embodiment in which the stop 14 is form-fittingly formed with the handle 4. A structurally beneficial construction of path limitation enabling limitation of handle 4 movement which can be illustrated with few components of handle can thus be achieved.

(12) In FIG. 4, an illustration according to line II-II from FIG. 1 is reproduced in turn. The position of the handle 4 in the case of emergency opening in which the handle was pulled out of the engagement area of the guide 11 is illustrated. The elevation 16 on the extension 10 was pulled out above the stop 14 so that the handle is disengaged with the guide and the motor vehicle lateral door 2. The force F2 is considerably greater than the force F1. As is apparent, a very large stroke H2 can be executed with the handle 4 by means of pulling the handle 4 out of the guide 11. The stroke H2 is also considerably greater than the stroke H1 and can be 30 mm, for example.

(13) By means of moving out of the handle or the handle component 4 out of the motor vehicle lateral door a very large stroke can thus be provided to operate the actuating means 8. The actuating means 8 is a cable in the illustrated exemplary embodiment. In addition to the function of the handle guide the guide 11 has a guide contour 17 in the form of a deflection 17 so that the cable 8 can be guided and deflected in the direction of the lock 6, for example.

(14) By means of the large stroke H2, which can also be more than 30 mm and in particular for example 50 mm, play during installation of the cable 8 can be offset and safe operation of the actuating lever 9 can be guaranteed on the lock 6.
