Grommet apparatus

An annular grommet apparatus for the passage of lines through a component opening, comprising:

• a cable passage portion, and
• a radially circumferential connecting portion for connecting the grommet apparatus to an edge region of the component opening in an assembly direction,
• wherein:
• the connecting portion has an inner and an outer stiffening wall, which are arranged substantially concentrically with respect to one another;
• the cable passage portion extends from the connecting portion in a direction counter to the assembly direction and is configured, at least in a region, with a funnel-shape such that a size of a cable passage opening through the cable passage portion, at least in the region, decreases when moving away from the connecting portion;
• the inner and outer stiffening walls are connected to one another by radially circumferentially arranged struts, wherein the struts are arranged to be equally spaced apart from one another;
• wherein each strut is bounded at a radially inner side by joinder with the inner stiffening wall and is bounded at a radially outer side by joinder with the outer stiffening wall;
• the connecting portion comprises a fastening portion, wherein the fastening portion comprises radially circumferentially arranged catching members for rearward engagement with an edge of a component lying in the assembly direction;
• and
• the inner stiffening wall includes an end edge facing in the assembly direction, wherein the outer stiffening wall includes an end edge facing in the assembly direction, wherein each strut includes an end edge, facing in the assembly direction, wherein the end edge of each strut is recessed, in the direction counter to the assembly direction, relative to the end edge of the inner stiffening wall and the end edge of the outer stiffening wall.
