A method for installing a fastening structure for at least one component on an attachment structure of a vehicle interior, the method comprising: providing a fastening structure comprising at least one unit, the unit comprising an elongate body, a first strut detachably coupled between the elongate body and a first fastening for fastening the unit to the attachment structure, a second strut detachably coupled between the elongate body and the first fastening and extending at an inclined angle to the elongate body, wherein the first strut and/or second strut are variably positionable with respect to the elongate body to provide tolerance compensation and are lockable in an end position; providing a jig comprising a support structure that is detachably couplable to the elongate body of the fastening structure, and one or more height adjustment devices on which the support structure is mounted, the height adjustment device being continuously adjustable and lockable in a desired position, adjusting the height adjustment device of the jig such that the first elongate body is arranged at a pre-determined height; moving the jig with respect to the attachment structure such that the first fastening engages with a first fixture of the attachment structure; fastening the first fastening to the first fixture to install the fastening structure on the attachment structure, whereby the variable positioning of the first strut and/or the second strut provides tolerance compensation between the elongate body and the first fixture, wherein the height adjustment device comprises a first part having an inclined inner surface and a second part having an inclined inner surface, the inclined inner surfaces (34, 36) cooperating to form a wedge-shaped gap, a wedge that is slidably arranged between the inclined inner surfaces (34, 36) of the first and second part (33, 35), wherein moving the height adjustment devices comprises moving the wedge in a substantially horizontal direction and causing the first and second parts (33, 35) to move apart in a substantially vertical direction, thus adjusting a height of the support structure such that the elongate body is arranged at the pre-determined height. providing a fastening structure comprising at least one unit, the unit comprising an elongate body, a first strut detachably coupled between the elongate body and a first fastening for fastening the unit to the attachment structure, a second strut detachably coupled between the elongate body and the first fastening and extending at an inclined angle to the elongate body, wherein the first strut and/or second strut are variably positionable with respect to the elongate body to provide tolerance compensation and are lockable in an end position; providing a jig comprising a support structure that is detachably couplable to the elongate body of the fastening structure, and one or more height adjustment devices on which the support structure is mounted, the height adjustment device being continuously adjustable and lockable in a desired position, adjusting the height adjustment device of the jig such that the first elongate body is arranged at a pre-determined height; moving the jig with respect to the attachment structure such that the first fastening engages with a first fixture of the attachment structure; fastening the first fastening to the first fixture to install the fastening structure on the attachment structure, whereby the variable positioning of the first strut and/or the second strut provides tolerance compensation between the elongate body and the first fixture, wherein the height adjustment device comprises a first part having an inclined inner surface and a second part having an inclined inner surface, the inclined inner surfaces (34, 36) cooperating to form a wedge-shaped gap, a wedge that is slidably arranged between the inclined inner surfaces (34, 36) of the first and second part (33, 35), wherein moving the height adjustment devices comprises moving the wedge in a substantially horizontal direction and causing the first and second parts (33, 35) to move apart in a substantially vertical direction, thus adjusting a height of the support structure such that the elongate body is arranged at the pre-determined height.
