Preferably, the securing element is a body with increased mechanical resistance. The securing element may alternatively be a body made of a reinforced plastic. Advantageously, the securing element is made of hardened steel, stainless steel or diecast zinc alloy (such as Zamak). Furthermore, it is conceivable that the carrier is pre-assembled with the lock cylinder, which together form a structural unit which is fastened on the inside of the movable part.

According to the invention, the securing element has a second arm which rests against the carrier on the inside of the movable part and / or is supported, in particular the second arm has shoulder elements which contact the carrier. This second arm is like the first arm designed as an extension of the securing element, which extends into the inner region of the movable part and can be held on the carrier via a suitable positive and / or non-positive connection. According to the present invention, it may be advantageous if attachment of the carrier takes place via the fastening means on the first arm of the securing element, wherein at the same time pressed during the fastening operation, the carrier in the direction of the inside of the movable part, and / or the securing element with its second arm aligns on the carrier until the second arm firmly contacts the carrier. Thus, it is conceivable that the carrier is attached to the first arm via the fastening means. At the same time a positive and non-positive connection of the carrier on the second arm, wherein this compound may be for example a clamp connection.

In a measure improving the invention, the lock cylinder is designed with a housing, wherein the housing is designed such that the housing is fastened by the fastening means on the first arm. Here, the housing serves as additional protection for the inner lock cylinder, which can be rotatably received within the housing. The housing may have an extension which extends in the direction of the first arm and is reliably fixable there on the fastening means. The inventive shape of the housing causes few components are required to ensure a reliable attachment of the lock cylinder and the lock cylinder housing. The mounting portion of the second arm is used simultaneously for attachment of the lock cylinder and the lock cylinder housing.

In addition, it is possible that the housing has a molded-on collar which protects the fastening means. This collar is advantageously formed on the extension of the lock cylinder housing, so that an additional protection for the fastener is provided, which is located behind the collar.

So that the protective cap is reliably held on the securing element, it can be provided that the securing element has at least one bearing point against which the protective cap rests. Furthermore, the securing element and / or the protective cap can have a seal in order to prevent harmful penetration of particles, moisture etc. into the inside of the movable part.

In FIG. 1 is schematically illustrated a motor vehicle, on the door 1, a handle is provided which has a door handle 3 on the outside. Laterally to the door handle 3, a protective cap 50 is arranged. Behind the protective cap 50, for example, a lock cylinder can be hidden, into which a key can be inserted manually in order to unlock or lock a lock of the door 1. This lock is not explicitly shown. According to FIG. 2 to FIG. 4 the area of the handle is shown on which the protective cap 50 is positioned. The protective cap 50 is detachably fastened to a securing element 10. The securing element 10 has different areas, so that this securing element 10 acts as a multi-functional component within the handle. The securing element 10 extends at least partially on the outer lining, in particular on the door panel 4 of the door 1. In addition, the securing element 10 is designed with an opening 13 in which a purely schematically illustrated lock cylinder 30 (see FIG. 4 ) is included. Here, the lock cylinder is flush with the surface 18 of the securing element 10th

In addition, the securing element 10 has an angled arm 11 which extends through an opening of the outer lining 4 of the door 1 and thus ends the door 1 on the inside. The arm 11 is angled and comprises a mounting portion 14, which is aligned in the present embodiment at an angle α to the outer panel 4, wherein the angle α is approximately between 20 ° and 30 °. The fastening portion 14 also has an opening 19 through which a fastening means 40 extends. The fastening means 40 is a screw element in the present exemplary embodiment. This screw member 40 connects the fuse element 10 with a support 2 of the handle, which extends inside the door 1. The carrier 2 of the handle has different functions, wherein in particular the carrier 2 may have a bearing point for the movable handle 3, which is not shown in detail. As a rule, the carrier 2 extends longitudinally to the vehicle direction within the door 1 and, as mentioned above, depending on the type of handle further functions, which will be disregarded in detail below. As in FIG. 2 to FIG. 4 can be seen, the carrier 2 can be fastened via the fastening means 40 on the securing element 10, whereby ultimately the carrier 2 can be reliably fixed to the inside of the door 1. As in FIG. 2 to FIG. 4 can be clearly seen, the fastening means 40 is completely inside the door 1. Further, the securing element 10 has a second arm 12, which extends like the first arm 11 in the interior of the door 1 itself. The second arm 12 is formed with two shoulder elements 16, on which the carrier 2 is supported. During assembly of the handle, a corresponding tightening of the screw member 40 takes place on the first arm 11 of the securing element 10, wherein at the same time the second arm 12 contacts the carrier 2 until it comes to reliable clamping on the shoulder element 16. Thus, the securing element 10 is reliably fixed to the door 1, wherein at the same time the inner support 2 is fixed inside the door 1.

As the FIG. 2 to FIG. 4 clarify, the securing element 10 has two fastening elements 15 in the form of openings 15, projecting into the locking elements 51 of the protective cap 50. According to the illustrated embodiment, namely, the protective cap 50 is connected via a latching connection with the securing element 10.

Furthermore, the protective cap 50 comprises a window 52, which is arranged laterally on the protective cap 50. The locking elements 51 are located inside the protective cap 50 in a cavity 53 which is formed by the protective cap 50. The locking elements 51 include projections 54 which can be actuated by an aid, such as an emergency key, to the locking elements 51 from their in the FIG. 2 to FIG. 4 to solve the set locking position. The projections 54 are chamfered according to the illustrated embodiment, so that an elastic deformation of the locking elements 51 via the aid, which is feasible in the cavity 53, is favored. The positioning of the locking elements 51 within the cavity 53 and the window 52 on the protective cap 50 is such that upon insertion of an aid through the window 52 into the cavity 53, the projections 54 of both locking elements 51 are actuated and thus both locking elements 51 from its detent position to be moved. Subsequently, the protective cap 50 is made of its in FIG. 2 to FIG. 4 shown position of the fuse element 10 removable. The latching elements 51 have at their free end a nose-like projection 55, which ensures that the latching connection of the protective cap 50 is ensured on the securing element 10.

The securing element 10 consists of a metallic material, here of a steel. In the opening 13, a dummy can be used as an alternative to the lock cylinder 30, which is useful, for example, in a handle, which is used on the passenger door. As FIG. 2 particularly illustrates, the lock cylinder 30 has a housing 31, wherein the housing 31 comprises an extension 33 which extends in the direction of the first arm 11. Namely, the case 31 is also fixed to the first arm 11 via the attachment means 40 like the carrier 2. In addition, the illustrated embodiment shows that the housing 31 has a collar 32 which lies protectively in front of the fastening means 40.

The embodiment shown according to FIG. 1 to FIG. 4 shows a handle, which is characterized by an increased security against burglary. This is partly because the fastener 40 is completely within the door 1 itself. In addition, the angled first arm 11 contributes to the fact that a destruction of the fastener 40 is difficult in the context of a break-in attempt from the outside. The collar 32 additionally protects the fastener 40 from external manipulation.

In FIG. 4 It is clear that the latching element 51 acts with its projection 55 on the securing element 10, in particular on the opening 15 of the securing element 10. Alternatively, it is also conceivable that the latching element 51 according to FIG. 5 through the opening 15 of the securing element 10 extends and engages with its projection 55 on the door 1, 4 and thus represents a reliable latching connection.

The protective cap 50 may be a 2-component component, wherein an outer body 56 is designed as a first element of the protective cap 50 and the latching elements 51 are provided as a second element of the protective cap 50, which in FIG. 2 and FIG. 3 is indicated schematically. The second element of the protective cap 50 is completely in FIG. 3 shown in FIG FIG. 2 the outer body 56 is shown and in dashed lines the second, inner element is indicated.
