Holding system and method for releasably attaching a flat item to an object and holding device for use in such a holding system

Method for releasably attaching a flat item (12) to an object (14), wherein a receiving structure (16) is associated with one of the flat item (12) or the object (14) and a retaining structure (18) is associated with the other of the two, which structures (16, 18) can engage with each other for releasably attaching the flat item (12) to the object (14),

• wherein the retaining structure (18) comprises at least two latching elements (20, 22) which are arranged opposite one another and movable relative to one another and which have latching sections (24) which are designed to engage with corresponding receiving sections (26;
• 26′) of the receiving structure (16), and the latching elements (20, 22) arranged opposite one another and movable relative to one another are movable relative to one another in such a way that a distance (a1) between the latching sections (24) can be varied, in order to switch the retaining structure (18) between a release position, in which the retaining structure (18) can be inserted into or removed from the receiving structure (16), and a latching position, in which the retaining structure (18) can be latched to the receiving structure (16), the method comprising the following steps:
• placing the receiving structure (16) obliquely on at least one first movable latching element (20), so that a first receiving section (26) of the receiving structure (16) engages behind a latching section (24) of the at least one first movable latching element (20), whereas a second receiving section (26′) of the receiving structure (16), which is arranged opposite the first receiving section (26), is arranged in front of the latching section (24) of at least one other fixedly arranged latching element (22), which is arranged opposite the at least one first movable latching element (20),
• with the receiving structure (16) obliquely placed on the at least one first movable latching element (20), applying a force to the obliquely placed receiving structure (16) in a direction which runs essentially parallel to a direction of movement (28) of the at least one first movable latching element (20), so that the at least one first movable latching element (20) is moved by the receiving structure (16) into a retracted position in which the retaining structure (18) is in a release position,
• with the at least one first movable latching element (20) in the retracted position, pivoting the receiving structure (16) from the inclined position towards the retaining structure (18), and
• with the receiving structure (16) pivoted towards the retaining structure (18), moving the at least one first movable latching element (20) together with the receiving structure (16) into an extended position in which the retaining structure (18) is in a latching position, wherein the second receiving section (26′) of the receiving structure (16) engages behind the latching section (24) of the at least one other fixedly arranged latching element (22).
