Sunshade system and method of manufacturing parts thereof

A sunshade system for use in a vehicle roof assembly, capable of opening or at least partly closing an opening below the vehicle roof assembly, said sunshade system comprising:

• a flexible sunscreen having at least a main part with two opposite lateral side edges, a leading edge and a trailing edge,
• a winding shaft for winding and unwinding the flexible sunscreen at its trailing edge,
• an operating beam attached to the leading edge of the flexible sunscreen,
• guiding strips laterally extending along, and attached to, each of lateral side edges of the main part and each of the guiding strips comprising:
• an inwardly foldable part capable of being folded inwardly towards a longitudinal centerline of the sunshade system in an acute angle with a middle part of each of the guiding strips and being folded flat in the same plane as the middle part when the flexible sunscreen is wound up onto the winding shaft, and
• a first hinge part extending in longitudinal direction of said strip,
• whereby the first hinge part is formed as a depression made in the guiding strips, and
• whereby each inwardly foldable part is connected to a remainder of the guiding strip by said first hinge part, and
• two opposed longitudinal guides for retaining therein in a transverse direction and slidably guiding therein in a longitudinal direction, at least the inwardly foldable parts, and at least a part of the middle part of the guiding strips, said guides being provided with locking members and with guide chambers for engaging at least the inwardly foldable parts of the flexible sunscreen for preventing said inwardly foldable parts from laterally moving out of the associated guide chamber of the longitudinal guides when the flexible sunscreen is at least partly unwound, wherein each guiding strip is made of thermoplastic material and comprises at least a second hinge part extending parallel to the first hinge part, longitudinally along a length of the guiding strip to form an opposite foldable part, wherein when each first hinge part is disposed in the associated guide chamber to move with sliding movement of each inwardly foldable part, wherein each second hinge part is in an unfolded state and disposed outside and spaced apart from the associated guide chamber.
