Abstract
A grommet assembly for installation in an opening of a vehicle body component is provided. The opening is dimensioned to receive a pipe therethrough. The grommet assembly comprises a first relatively stiff component and a second relatively flexible component. The first component has retention elements formed therewith to secure the pipe to the grommet assembly. The second component is sized to be securely mounted in the body component opening. The second component is at least partially overmolded onto the first component. The grommet assembly is pre-mounted on the pipe and is configured to keep the pipe generally centered in the body component opening.
Claims19
A grommet assembly for installation in an opening of a vehicle body component, the opening being dimensioned to receive a pipe therethrough, the grommet assembly comprising:
- a first relatively stiff component having retention elements formed therewith to secure the pipe to the first component and the grommet assembly, the first component including a first end wall, a second end wall and an outer surface;
- and
- a second relatively flexible component sized to be securely mounted in the body component opening, the second component including a first end and a second end and is at least partially overmolded onto the outer surface of the first component such that the second component is non-removably connected to the first component, and an axial length measured from the first end to the second end of the second component is less than an axial length measured from the first end wall to the second end wall of the first component such that at least one of the first and second end walls of the first component project outwardly from at least one of the first and second ends of the second component,
- wherein the grommet assembly is pre-mounted on the pipe and is configured to keep the pipe generally centered in the body component opening.
A vehicle brake pipe assembly comprising:
- a body component having an opening formed therein, the body component separating an engine compartment and a wheel house;
- a brake pipe configured to traverse the opening;
- and
- a grommet assembly for installation in the opening for routing the brake pipe through the opening, the grommet assembly including a generally rigid clip configured to be securely mounted to the brake pipe and an elastomeric component configured to be securely mounted in the opening, the elastomeric component at least partially encapsulating an outer surface of the clip,
- wherein the grommet assembly is secured to the brake pipe prior to mounting in the opening and provides a fixing point for the brake pipe at a center of the opening,
- wherein the grommet assembly has an increased thickness relative to the body component to resist deformation caused by brake pipe misalignment through the opening,
- wherein the elastomeric component includes a slotted opening for passage of the brake pipe into the clip, and the clip includes a top wall having a pair of opposed arms defining a clip opening, and the slotted opening is defined by a first wall and a second wall, the first and second walls projecting toward the clip top wall.
A vehicle brake pipe assembly comprising:
- a body component having an opening formed therein, the body component separating an engine compartment and a wheel house;
- a brake pipe configured to traverse the opening;
- and
- a grommet assembly pre-mounted on the brake pipe for installation in the opening, the grommet assembly including:
- a generally rigid clip configured to be securely mounted to the brake pipe, the clip including an outer surface having a radial ridge, and
- a generally C-shaped elastomeric component configured to be securely mounted in the opening, the elastomeric component overmolded onto the radial ridge of the clip, the radial ridge improving retention of the clip within the elastomeric component,
- wherein the elastomeric component is press fit within the opening, the elastomeric component, after being securely mounted in the opening, configured to bear down against the outer surface of the clip and compress the clip against the pipe.
A method of installing a brake pipe to a body component of a vehicle, the body component having an opening formed therein for receiving the brake pipe, the method comprising:
- providing a generally rigid clip configured to be securely mounted to the brake pipe;
- overmolding the clip with an elastomeric material, the clip and overmolded elastomeric material together forming a grommet assembly for routing the brake pipe through the opening;
- positioning the brake pipe through the body component opening;
- securing the grommet assembly to the brake pipe prior to mounting of the grommet assembly in the opening;
- and
- mounting the secured grommet assembly in the body component opening, the grommet assembly providing a fixing point for the brake pipe at a center of the body component opening.
