## Title
Grip for a motor vehicle

## Abstract

A grip consists of two grip shells which can be connected with one another by gluing and in which a supporting carrier is arranged. The supporting carrier has connection elements on the end side for a fastening to a vehicle structure.

## Background
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to a grip for a motor vehicle consisting of two half shells which can be connected with one another and have a supporting carrier situated on the inside, and the holding grip can be connected particularly with a transmission tunnel of the motor vehicle or with a vehicle structure.
FR 15 62 374 discloses a grip in which a reinforcing core is embedded. Furthermore, a grip consisting of two shell bodies is described in DE 76 23 712 U, in which the shell bodies can be assembled and are connected with one another by projections and indentations arranged on the joining surface and mutually engaging in the manner of snap fasteners. In addition, DE 87 06 310 U1 discloses a roof holding grip consisting of two shells which can be assembled, in which case one shell comprises a hook on a connecting edge, which hook can be fitted into a slot at the opposite connecting edge of the other shell.
An object of the present invention is to provide a holding grip for a motor vehicle which can easily be produced and assembled, has a stable construction and has fastening possibilities on a vehicle component, for example, on a transmission tunnel of the vehicle body.
According to the invention, this object is achieved by providing that a supporting carrier is arranged between the two semicircular grip shells made of plastic, which supporting carrier has an I-shaped profile in its cross-section and, at one free end, has a connection element with fastening bores which projects from the grip shells and, at its other end facing away from this connection element, has a sleeve-type other connection element which is arranged inside the grip shell and has a threaded bore for a screwing device for a fastening to the vehicle structure.
Among the principal advantages achieved by way of the holding grip formed of two plastic shells are that an inserted metallic core or a core consisting of a plastic material forms a supporting carrier which provides the grip with an optimal stability, prevents a bending due to a load and can be fastened in a simple manner.
According to the present invention, this is essentially achieved in that a, for example, metallic supporting carrier is arranged between the two semicircular grip shells made of plastic. In its cross-section, this supporting carrier consists of an I-section and is provided with a connection element of an angular cross-section which projects out of the grip shells and has fastening bores. On its other free end, a sleeve-type other connection element is provided which is molded on, is arranged inside the grip shells and is provided with a threaded bore for a screwing device for a fastening to the vehicle.
Preferably, the supporting carrier consisting of an I-section points with its flanges to the connecting edges of the grip shells, and a web of the I-section extends in a common plane with the connecting edges, and the interior surfaces of the grip shells are supported on the front edges of the flanges. On one hand, this arrangement simplifies the assembly of the two grip shells and, on the other hand, the continuous supporting carrier with end-side fastening possibilities permits a stable linkage to the vehicle structure; in this particular case, to a transmission tunnel of the vehicle.
Furthermore, for a simple connection of the supporting carrier with a grip shell, it is provided according to the invention that at least one welding dome or a catch is arranged on an interior surface of a grip shell, on which the supporting carrier is fastened by hot-riveting. As a result, the supporting carrier can easily be firmly connected with one grip shell, so that no relative displacement can take place between the supporting carrier and the grip shells. For the precise mutual fixing of the grip shells, one grip shell according to the present invention has at least one centering bush on the interior surface of one grip shell with a centering pin of the other grip shell being fitted into the centering bush for aligning the two grip shells with respect to one another.
According to the invention, the connection of the holding grip takes place such that the sleeve-type connection element of the supporting carrier is arranged to fill out the space between the two grip shells, and an insertion piece with a threaded bore is held between webs of the connection element. Furthermore, the projecting connection element of the supporting carrier has at least one continuous bore for a fastening screw which extends transversely to the grip in the installed position, and the connection element as well as screws are covered by way of a cap adjoining the grip shell. As a result of this construction of the two free ends of the supporting carrier with connection elements, fastenings can be implemented which are easy to produce and maximal forces acting upon the grip can be absorbed without the possibility that the grip may detach from the vehicle structure when it is subjected to a load.

DETAILED DESCRIPTION OF THE DRAWINGS
The holding grip 1 comprises two semicircular grip shells 2, 3 mutually connected, for example, by a gluing-together or locking-together. A supporting carrier 4, which in its cross-section consists of an I-profile, is arranged in an embedded manner inside these grip shells 2, 3 and which in each case has connection elements 5, 6 on the end side for a fastening to the vehicle structure.
The connection elements 5, 6 are constructed in one piece with the supporting carrier 4. Connection element 5 extends out of the grip shells 2, 3 in a bare manner or exposed and is covered by a shell 8. This connection element 5 has, for example, a square cross-section and has at least two transversely extending bores 9, 10 which extend to the grip 1 and accommodate the fastening screws 11 which can be connected with the vehicle structure 12.
The additional connection element 6 consists of a sleeve-shaped receiving element 13 which is arranged to be embedded in the two grip shells 2, 3. In the connection element 6, a receiving bore 14 (FIG. 3) for a fastening screw (15) is arranged which establishes a fixed connection to the vehicle structure.
The profile of the supporting carrier 4 is situated with its web 15 in a common plane X-X with abutting connection edges 16, 16a. The grip shells 2, 3 are supported on front edges of the flanges 18, 19 of the profile.
The connecting edges 16, 16a and 17, 17a of the grip shells 2, 3 are arranged to be mutually overlapping. The connecting edges 16a, 17a of grip shell 16 have a shoulder 20, 21 into which the opposite connecting edges 16, 17 are inserted. As seen in FIG. 7, one indentation 22, 23 respectively is formed in the connection area of the edges 16, 16a and 17, 17a, and a seam of a covering made of leather or another material for the grip 1 is situated in the indentation 22, 23. The other material may be a fabric, a foil, a leather imitation or the like.
The supporting carrier 4 can be fixed on a grip shell 2, 3 by a welding dome 24 (FIG. 5) which is hot-riveted for this purpose. The welding dome 24 comprises, for example, two spaced ribs 25 and 26.
For fixing the two grip shells 2, 3 with respect to one another, centering pins 27 (FIG. 2) with a cross-shaped cross-section are provided on one grip shell 2 or 3 and can each be fitted into a centering bush 28 to hold the two grip shells 2, 3 in a predetermined connection position with respect to one another. The grip shells 2, 3 can be provided with a covering of leather or another covering.
The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
