## Abstract

A grommet apparatus is provided for the passage of lines through a substantially slot-shaped component opening. The grommet apparatus includes, among other things, a tubular, resiliently expandable cable passage portion extending along a central axis between a first end and a second end and a connection portion having a flange-like edge region surrounding the cable passage portion circumferentially for fastening the grommet apparatus in the component opening, comprising at least a plurality of first stiffening ribs that extend radially aligned outwardly circumferentially while being spaced apart from one another from one end of the cable passage portion to the central axis.

## Claims

### Claim 1

A grommet apparatus for the passage of lines through a substantially slot-shaped component opening, comprising:
a tubular, resiliently expandable cable passage portion extending along a central axis between a first end and a second end;
a connection portion having a flange-like edge region surrounding the cable passage portion circumferentially for fastening the grommet apparatus in the component opening, comprising at least a plurality of first stiffening ribs that extend radially aligned outwardly circumferentially while being spaced apart from one another from one end of the cable passage portion to the central axis.

### Claim 2 (depends on 1)

The grommet apparatus according to claim 1, wherein the contour profile of the edge region of the connection portion is configured to complement the contour profile of the component opening in such a way that the connection portion can be attached in the component opening by way of radial pressing.

### Claim 3 (depends on 1)

The grommet apparatus according to claim 1, wherein the contour profile of the edge region is substantially slot-shaped or oval-shaped.

### Claim 4 (depends on 1)

The grommet apparatus according to claim 1, wherein the edge region of the connection portion is formed from two opposed first side edges and two opposed second side edges, respectively, wherein the second side edges are longer than the first side edges, and the first side edges and/or second side edges are each domed outwardly.

### Claim 5 (depends on 1)

The grommet apparatus according to claim 1, wherein the connection portion comprises at least one second stiffening rib, which at least partially radially surrounds the cable passage portion in a circumferential manner and is substantially orthogonally aligned in relation to the first stiffening ribs.

### Claim 6 (depends on 1)

The grommet apparatus according to claim 1, wherein the connection portion comprises a fastening portion, wherein the fastening portion comprises at least one radially circumferentially arranged locking means for rearwardly engaging with an edge of the component opening lying in the assembly direction.

### Claim 7 (depends on 6)

The grommet apparatus according to claim 6, wherein the locking means comprises a locking edge arranged counter to the direction of assembly.

### Claim 8 (depends on 1)

The grommet apparatus according to claim 1, wherein the connection portion comprises a sealing portion, wherein the sealing portion comprises a radially circumferential sealing lip extending substantially in the direction of assembly.

### Claim 9 (depends on 1)

The grommet apparatus according to claim 1, wherein the cable passage portion is arranged eccentrically circumferentially on one end of the cable passage portion.

### Claim 10 (depends on 1)

The grommet apparatus according to claim 1, wherein the connection portion is integrally formed with the cable passage portion.
