Component system for fixing a trim part and motor vehicle

Abstract

A component system for fixing a trim part in a defined position as well as a motor vehicle, in particular a passenger car, is provided. The component system has a trim part that is to be fixed in relation to a motor vehicle body component, in particular a headliner, a trim support for supporting the trim part as well as a counter-pressure device for applying a first force to a first area of the trim part. At least one section of the trim support is disposed on a side of the first area opposite the counter-pressure device for applying a second force oriented in an opposite direction from the first force to the first area. A second area of the trim part is disposed on the side of the trim support opposite the first area and thus forms a visible side of the trim part.

DETAILED DESCRIPTION

(7) FIGS. 1 and 2 have already been discussed to explain the conventional art.

(8) FIG. 3 shows a section of the side connecting area of a trim part 20, namely a headliner, on motor vehicle body component 35, namely an inner side part 30. Similarly to FIG. 1, the section runs perpendicularly to the longitudinal extension direction of the C pillar, viewed in the direction counter to the direction of travel of the motor vehicle, and shows the right side or passenger's side of the motor vehicle.

(9) At the illustrated position the motor vehicle shell comprises, in addition to inner side part 30, a rear inner side part 31, a rear connecting part 32 and an outer side part 33. Together, they form part of the roof structure. In the outer area shown on the left, a sealing strip 68 partially faced with an outer molding 70 abuts outer side part 33. It holds side window 66, which is fastened to outer side part 33 with the aid of an adhesive bead 72.

(10) Outer side part 33, rear connecting part 32 and inner side part 30 run in parallel to each other in sections in their lower areas and are fixed to each other in these areas. Outer side part 33 and connecting part 32 end in a shared front side, while inner side part 30 disposed adjacent thereto extends farther downwardly in the direction of trim part 20. Inner side part 30 is the motor vehicle body component 35 which faces interior 60 of the motor vehicle in the illustrated proper arrangement of component system 10 in a motor vehicle.

(11) The lower section of inner side part 30, a motor vehicle body component 35, is designed as a counter-pressure device 12, which includes a contact surface 14 for applying a first force 41 to an underlying first area 21 of trim part 20. Together with trim part 20 and trim support 50, they form component system 10 according to the invention, which fixes trim part 20 in a defined position in relation to motor vehicle body component 35. Alternatively or additionally to inner side part 30, rear connecting part 32 and/or outer side par\ 33 could also be lengthened accordingly and used as counter-pressure device 12.

(12) Similarly to FIG. 1, trim part 20, namely the headliner limiting motor vehicle interior 60 in the upward direction, is also held by a trim holder 50 in this case. The trim part is disposed in a U shape around periphery 54 of trim support 50 shown on the left, namely it is bent therearound. First area 21 of trim part 20 is situated above corresponding section 52 of trim support 50, and a second area 22 of trim part 20 is situated on the side of trim support 50 opposite first area 21, i.e. it is situated below section 52.

(13) A section 52 of trim support 50 is disposed on the side of first area 21 of trim part 20 opposite counter-pressure device 12 for the purpose of applying a second force 42 oriented in the opposite direction from first force 41 to first area 21 of trim part 20. Trim part 20 is thus compressed or clamped from two sides, namely by trim support 50 and by counter-pressure device 12.

(14) It is apparent that trim part 20 has a reduced thickness in active area 24 of first force 41, in which second force 42 also acts upon trim part 20, than in area 26 adjacent to active area 24. This is the result of a deformation of trim part 20, a foam part, induced by the application of first force 41 and second force 42. It is thus apparent that trim part 20 is, on the one hand, pressed against trim support 50 by the first force and is thus fastened thereto, and, on the other hand, an upward displacement of trim support 50 and trim part 20 is effectively prevented by counter-pressure device 12.

(15) Counter-pressure device 12 and trim support 50 are disposed at a distance A of less than 0.5 mm from each other in active area 24 of first force 41 and the second force. Accordingly, the trim part is compressed to the aforementioned thickness in this area.

(16) Similarly to FIG. 2, FIG. 4 shows the pattern resulting from the structure according to the invention at the joint between trim part 20 and pillar trim 62, the trim of the C pillar in this case. Viewed from the outside through the side window, in the direction of the right side or driver's side of a motor vehicle comprising component system 10 according to the invention, the bent area of trim part 20 is shown from the outside. Area 21 of trim part 20 is at the top and second area 22 thereof is situated therebeneath.

(17) A gap is apparent between upper first area 21 of trim part 20 and the motor vehicle shell, namely outer side part 33. A portion of counter-pressure device 12 is visible therein, which is implemented, as described, with the aid of a section of a motor vehicle body component 35, namely inner side part 30.

(18) On the right side, it is apparent that trim part 20 bent around the trim support is inserted into pillar trim 62 or is held thereby. Pillar trim 62 functions as a holding device for holding trim part 20 or trim support 50. It is configured and disposed on trim part 20 or trim support 50 for the purpose of applying a third force 43 oriented in the opposite direction from first force 41 and thus holds the latter in the desired position.

(19) Counter-pressure device 12 is used to effectively protect trim support 50 and trim part 20 against an upward displacement. The detent tab mentioned with reference to FIG. 2 may thus be properly engaged here, so that the gap shown in FIG. 2 does not occur in this case.

(20) FIG. 5 shows counter-pressure device 12 designed as a section of motor vehicle body component 35, namely inner side part 30. The latter has an essentially planar contact surface 14, which is configured to apply first force 41 and has a length L of 15 mm and a height H of 3.6 mm. It is thus an elongation in areas of inner side part 30 manufactured from sheet metal and having a thickness of 1.5 mm.

(21) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims
