Shading device for a transparent surface part of a motor vehicle

A shading device for a transparent surface part of a motor vehicle, comprising:

• a flexible and rectangular shading structure which can be displaced between a rest position, in which the shading structure is stowed in a compact manner, and a shading position, in which the shading structure covers the transparent surface part in a vehicle interior;
• two non-parallel lateral guide arrangements which are fixed with respect to the vehicle and which flank a displacement travel of the shading structure on opposite sides thereof, and which taper towards each other at tops thereof;
• a substantially non-flexible pull-out profile which is arranged on a front face end region of the shading structure as viewed in a pulling-out direction;
• a transverse guide strip that extends continuously over an entire width of the shading structure transversely with respect to the pulling-out direction, the guide strip connecting the shading structure to the pull-out profile such that the shading structure is not directly connected to the pull-out profile;
• the pull-out profile, at opposite face sides thereof, being displaceable in parallel fashion in each case by one guide carriage in a respective one of the lateral guide arrangements by way of a drive which engages on the guide carriage;
• and
• a pair of lateral shading structure sections of the shading structure protruding, in a manner dependent on a displacement travel of the shading structure, into lateral receiving spaces which are configured to be fixed with respect to the vehicle and which are assigned to the guide arrangements;
• wherein each of the lateral shading structure sections comprises at least two support bodies which are spaced apart from one another in the pulling-out direction of the shading structure and a thickness of which is greater than a thickness of the shading structure and which are guided in transversely supported fashion with play in complementary support channel sections of the receiving spaces, each of the at least two support bodies on each lateral shading structure section moving along a single line as the shading structure moves between the rest position and the shading position;
• and
• wherein each of the support channel sections of the receiving spaces includes, in cross-section, a pair of elongate opposite aligned walls having an open entrance area at one end of the pair of walls and an end area at the other end of the pair of walls, each of the support bodies moving within the support channel sections of the receiving spaces flanked by the pair of elongate opposite aligned walls between the open entrance area of the support channel sections of the receiving spaces and the end area, with the support bodies moving toward and away from the open entrance area and the end area as the shading structure moves between the rest position and the shading position.
