DETAILED DESCRIPTION

[0074] FIG. 1A shows the initial state, FIG. 1B shows the state with nut elements 20, 20′ arranged by the positioning strip, and FIG. 1C shows the definitively installed state on a vehicle component 200. The configuration is such that the installation system 1 has: [0075] a carrier strip 10, which can be pushed into the box profile 100, [0076] two nut elements 20, 20′ for prepositioning on the carrier strip 10,
wherein the nut elements 20, 20′ are designed to be prepositioned in a releasable manner on the carrier strip 10, and wherein the installation system 1 has a positioning strip 30, which can be displaced relative to the carrier strip 10 and is designed to arrange the nut elements 20, 20′, in the state in which the latter have been prepositioned on the carrier strip 10, on a respective opening 102, 102′ of the box profile 100.

[0077] Installation contains the following steps: [0078] prepositioning the nut elements 20, 20′ on the carrier strip 10, [0079] introducing the carrier strip 10, with the nut elements 20, 20, into the box profile 100, [0080] installing the vehicle component 200 on the box profile 100 by screw-connection of the nut elements 20, 20′ using a respective screw guided through a respective opening 102, 102′ of the box profile 100;
wherein the method,
prior to installation, has the following step: [0081] arranging the nut elements 20, 20′ on the openings 102, 102′ by means of the positioning strip 30;
and, following or prior to installation, but following the arrangement of the nut elements 20, 20′, has the following step: [0082] guiding the positioning strip 30 and the carrier strip 10 (separate guidance in this example) out of the box profile 100 and, in the process, releasing the nut elements 20, 20′ from the carrier strip 10.

[0083] A more detailed description of FIGS. 2A-2B follows hereinbelow. FIG. 2A shows the nut element 20 in the state in which it has been pushed upward by the positioning strip 30 and detached from the carrier strip 10—to improve clarity, the nut element is shown without the box profile 100, although said pushing-upward action takes place within the box profile 100. Also for reasons of clarity, there are no other nut elements 20′ illustrated, although this installation system has five nut elements. The following description also applies to the other four nut elements (not shown). FIG. 2B shows the nut element in the state in which it has been latched on the box profile 100. In contrast to the configuration in FIGS. 1A-1C, the nut element 20 in this configuration has already been released from the carrier strip by virtue of the nut element 20 being arranged on the opening 102 by means of the positioning strip 30. The configuration is such that the nut element 20 is designed to be retained on the opening 102 on the inner side of the side of the box profile 100 in which the opening 102 is made, by means of a latching connection between the nut element 20 and the box profile 100. The configuration is such that the nut element 20 has four latching hooks 26, 26′, 26′″ (fourth latching hook concealed), which are designed to hook in behind a total of two protrusions 103 (second protrusion not shown in FIG. 2B, but is located in a corresponding position, mirrored along section planes, opposite the protrusion 103) of the box profile 100 and thus to retain the nut element 20 on the opening 102. The configuration is such that the nut element 20 is designed to be released from the carrier strip 10 by virtue of the positioning strip 30 being displaced in relation to the carrier strip 10. The configuration is such that the nut element 20 is designed to be prepositioned on the carrier strip via a recess 11, in this case a slot, and a corresponding protrusion 22, in this example a nipple, by virtue of the recess 11 and protrusion 22 being fitted one inside the other, and therefore movement of the nut element 20 in the longitudinal direction L is restricted and movement in the direction of the opening 102 when the carrier strip 10 has been pushed into the box profile 100 is possible. In this example, the carrier strip 10 has the recess 11 in the form of a slot which is oriented in the direction of the opening 102, and is open toward the latter, and the nut element 20 has the protrusion 22 in the form of a corresponding nipple, which is guided in the slot. In this example, two recesses 11 and protrusions 22 are provided for retaining purposes for a nut element 20 (concealed on the rear side in FIG. 2A). The configuration is such that the nut element 20 has two centering elements 23, 23′, by means of which it is possible to orient the nut element 20 on the opening 102 of the box profile 100. The configuration is such that the centering elements 23, 23′ are in the form of stubs, which are designed to penetrate into centering recesses 104, 104′ located alongside the opening 102 of the box profile 100, in this example in the same wall of the box profile 100. In this example, the stub tapers in the direction of its tip. The configuration is such that the nut element 20 has a threaded part 24 and a preassembly part 25. The preassembly part 25 has the two protrusions 22 for prepositioning on the carrier strip 10 and the four latching hooks 26, 26″, 26′″ for latching to the box profile 100 and also has the centering elements 23, 23′. The configuration is such that the threaded part 24 is produced from metal and the preassembly part 25 is produced from plastic. In this example, the threaded part 24 and preassembly part 25 are produced separately and then assembled. The configuration is such that the carrier strip 10 is a U-shaped profile strip. In this example, the recesses 11 are made on opposite side walls of the U-shaped profile. In this example, the U-shaped profile is open in the direction of the openings 102 of the box profile 100. The configuration is such that the positioning strip 30 is guided in the carrier strip 10. In this example, the positioning strip has a width B1 which is slightly smaller than an inner width B2 of the carrier strip. The configuration is such that the positioning strip 30 has at least one ramp 31, which is designed to come into contact behind the nut element 20 prepositioned in the carrier strip 10 and to shift the nut element 20 in the direction of the opening 102 by virtue of being displaced in relation to the carrier strip 10.

[0084] In this example, the nut elements 20 are preassembled on the openings 102 via a preassembly method, containing the following steps: [0085] prepositioning the nut elements 20 on a carrier strip 10, [0086] introducing the carrier strip 10, with the nut elements 20, into the box profile 100, [0087] releasing the nut elements 20 from the carrier strip 10 and arranging the nut elements 20 on the opening, and also latching the nut elements 20 to the box profile 100 on the inner side of the box profile 100, by means of the positioning strip 30 by virtue of the positioning strip 30 being displaced in the longitudinal direction relative to the carrier strip; [0088] guiding the positioning strip 30 and the carrier strip 10 out of the box profile 100.

[0089] Since the nut elements 20 were released from the carrier strip 10 by the positioning strip 30, it is possible for the positioning strip 30 and the carrier strip 10 to be guided together out of the box profile 100.

[0090] A more detailed description of FIG. 3 follows hereinbelow. The configuration is such that the nut element 20 is configured as in FIGS. 2A-2B. The nut element 20 has four latching hooks 26, 26′, 26′″, which are designed to hook in behind a protrusion 103 of the box profile 100 and thus to retain the nut element 20 on the opening 102. In this example, the nut element 20 has a threaded part 24 and a preassembly part 25, wherein the threaded part 24 is produced from metal and the preassembly part 25 is produced from plastic. In this example, the nut element 20 has at least two centering elements 23, 23′, by means of which it is possible to orient the nut element 20 on the opening 102 of the box profile 100, wherein the centering elements 23, 23′ here are in the form of stubs, which are designed to penetrate into a respective centering recess 104 located alongside the opening 102 of the box profile 100, in this example in the same wall of the box profile 100. The nut element 20 has a protrusion 22 in the form of a nipple for guiding in the slot of the carrier strip 10. In this example, at least two protrusions 22 are provided for retaining purposes for a nut element 20. The preassembly part 25 has the two protrusions 22 for prepositioning on the carrier strip 10 and the four latching hooks 26, 26″, 26′″ for latching to the box profile 100 and also has the centering elements 23, 23′.
