Description

DRAWINGS

(1) Embodiments will be illustrated by way of example in the drawings and explained in the description below.

(2) FIG. 1 illustrates a plan view of a holding element of a motor vehicle tank, in accordance with embodiments.

(3) FIG. 2 illustrates a sectional view of the holding element of FIG. 1.

DESCRIPTION

(4) FIGS. 1 and 2 respectively illustrate a holding element of a motor vehicle tank, in accordance with embodiments.

(5) A motor vehicle tank (not illustrated) comprises a tank container formed by a tank wall. A component is fastened to the tank wall in the interior of the tank container via the holding element 1. The holding element 1 substantially forms a plane, namely, a circle. The holding element 1 has three attachment points 2 for fastening the holding element 1 to the tank wall. The attachment points 2 are designed as projecting screw domes.

(6) In an opposite direction to the attachment points 2, a plurality of fastening elements 3 for fastening the component to the holding element 1 project from the plane of the holding element 1 (See, FIG. 2). In a plan view of the plane (See, FIG. 1), the fastening elements 3 are each arranged between the attachment points 2. The fastening elements 3 each form a hook or clip for hooking in the component to be fastened. In each case, two adjacent attachment points 2 are connected to one another by circular-arc-shaped spring elements 4, which are referred to herein as “attachment spring elements” 5. Owing to their thin shape and the material used, the attachment spring elements 5 are formed in such a way that they can yield and have a resilient effect.

(7) A round surface 6 is connected in several sections of its outer circumference to the attachment spring elements 5 of the holding element 1. The surface 6 itself also is composed of a soft material and likewise serves as a spring element 4. The surface 6 has stiffening ribs 7, the stiffening ribs 7 extending symmetrically or asymmetrically on the surface 6 in order to bring about a desired strength and desired resilient properties of the surface 6. The fastening elements 3 are formed on the edge of the surface 6.

(8) A component to be fastened, such as, for example, a roll-over valve, a pressure-maintaining valve or a pump, can be fastened to the fastening elements 3 from below (FIG. 2) and is then below the surface 6, and thus, below the plane of the holding element 1, i.e., on an opposite side of the holding element 1 from the side which is fastened to the tank.

(9) The holding element 1 thus has spring elements 4 between the attachment points 2 and the fastening elements 3, and therefore, the component is fastened to the tank wall in a spring-elastically decoupled manner via the holding element 1, and thus noises are transmitted to a lesser degree from the component to the tank wall and into the motor vehicle.

(10) The terms “coupled,” “attached,” or “connected” may be used herein to refer to any type of relationship, direct or indirect, between the components in question, and may apply to electrical, mechanical, fluid, optical, electromagnetic, electromechanical or other connections. In addition, the terms “first,” “second,” etc. are used herein only to facilitate discussion, and carry no particular temporal or chronological significance unless otherwise indicated.

(11) Those skilled in the art will appreciate from the foregoing description that the broad techniques of the embodiments can be implemented in a variety of forms. Therefore, while the embodiments have been described in connection with particular examples thereof, the true scope of the embodiments should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification, and following claims.
