Abstract
A winding mechanism for a sunscreen for use in an open roof construction for a vehicle includes a winding tube which is rotatable around a central axis of rotation for winding and unwinding the sunscreen. At least one spring member biases the winding tube in a direction for winding the sunscreen thereon. A sleeve protects the spring member from causing noises and is manufactured of a flexible layered material, having at least a first and a second layer connected to each other and having different properties so that the layer in contact with the spring is wear resistant and the other layer has an elastic ability.
Claims25
A winding mechanism for a sunscreen, for use in an open roof construction for a vehicle, comprising:
- a winding tube being rotatable around a central axis of rotation configured to wind and unwind the sunscreen;
- at least one spring member configured to bias the winding tube in a direction for winding the sunscreen thereon;
- and
- a sleeve configured to engage the spring member and inhibit noise from the spring member, wherein the sleeve comprises a flexible layered material, having at least a first and a second layer connected to each other and having different properties;
- wherein the flexible layered material of the sleeve is manufactured from one thread, woven in such a pattern so as to form said at least two layers.
A rollo assembly comprising:
- a winding tube being rotatable around a central axis;
- a shaft extending longitudinally within the winding tube;
- at least one spring member configured to bias the winding tube in a direction for winding the sunscreen thereon;
- a sleeve disposed between the spring and the shaft, wherein the sleeve comprises a flexible layered material, having at least a first and a second layer connected to each other and having different properties, wherein the second layer is made of dampening material having a dampening effect on physical forces or impacts applied to either an inner or outer surface of the sleeve, and wherein said second layer has a three dimensional open structure configured to dampen movement of the spring member;
- a flexible panel with an end secured to the winding tube, the panel being configured to be wound upon and unwound from the winding tube;
- and
- a pair of guides configured to guide opposite edges of the panel as the panel is wound upon and unwound from the winding tube;
- and
- a beam secured to an end of the panel remote from the end secured to the winding tube, the beam extending transversely between the guides.
