Abstract
A double window shade arrangement for a divided window of a motor vehicle, the window shade arrangement includes two separate winding shafts that are arranged on the window at arbitrary angles relative to one another. Window shade strips assigned to the respective winding shafts are moved in at least one direction with the aid of a common driving motor. For this purpose, the electric motor can be coupled to the free edges of the window shade strips or directly coupled to the winding shafts.
Claims29
In an automobile having two windows sized and configured differently from each other, a window shade arrangement comprising a first winding shaft (14, 35) rotatably supported adjacent a window edge (7), a first window shade strip (16, 38) shaped to conform generally to a first one of said windows and having one end attached to said first winding shaft (14, 35) and a free edge (37, 39) that can be moved away from the first winding shaft (14, 35), a second winding shaft (14, 35) rotatably supported adjacent to another window edge (7), a second window shade strip (16, 38) shaped to conform generally to a second of said windows and differently from said first window shade strip, said second window shade strip (16, 38) being attached to said second winding shaft (14, 35) and having a free edge (17, 39) that can be moved away from the second winding shaft (14, 35), a single drive unit (19, 61) operatively coupled to each of said window shade strips (16, 39) for moving said window shade strips (16, 38) in at least one direction in response to operation of the drive unit (19,61) into respective overlying relation with said two windows, and said drive unit being operable for moving one of said window shade strips a greater distance than the other of said window shade strips.
In a motor vehicle having windows, a window shade arrangement comprising a first winding shaft (14, 35) rotatably supported adjacent a window edge (7), a first window shade strip (16, 38) having one end attached to said first winding shaft (14,35) and a free edge (37, 39) that can be moved away from the first winding shaft (14, 35), a first rewind drive unit 15 for turning the first winding shaft (14, 35) in a direction in which the first window shade strip (16, 38) is wound up on the winding shaft, a second winding shaft (14, 35) rotatably supported adjacent to another window edge (7), a second window shade strip (16, 38) attached to said second winding shaft (14, 35) and having a free edge (17, 39) that can be moved away from the second winding shaft (14, 35), a second rewind drive unit 15 for turning the second winding shaft (14, 35) in a direction in which the second window shade strip (16, 38) is wound up on the winding shaft, a single power drive unit (19) that cooperates with the free edge (17, 39) of only one window shade strip (16, 38) in order to unwind the window shade strip (16, 38) from its corresponding winding shaft (14, 35), and a drive mechanism (56) connected to the winding shaft (14, 35) for the window shade strip (16, 38) with which the single power drive unit (19) cooperates for transforming rotational movement of the winding shaft (14, 35) into linear movement of an output element (38) coupled to the free edge (17, 38) of the other window shade strip (16, 38) for enabling free edges of said window shade strips to be simultaneously moved away from their respective winding shafts as an incident to operation of said single power drive unit.
In a motor vehicle having windows, a window shade arrangement comprising a first winding shaft (14, 35) rotatably supported adjacent a window edge (7), a first window shade strip (16, 38) having one end attached to said first winding shaft (14, 35) and a free edge (37, 39) that can be moved away from the first winding shaft (14, 35), a second winding shaft (14, 35) rotatably supported adjacent to another window edge (7), a second window shade strip (16, 38) attached to said second winding shaft (14, 35) and having a free edge (17, 39) that can be moved away from the second winding shaft (14, 35), a single drive unit (19, 61) operatively coupled to each of said window shade strips (16, 39) for moving said window shade strips (16, 38) in at least one direction in response to operation of the drive unit (19,61), said drive unit being decoupleable from one of said window shade strips (16, 19) during movement of the window shade strip in at least one direction so as to enable the drive to move the other of window shade strips a greater distance than the one window shade strip.
In a motor vehicle having windows, a window shade arrangement comprising a first winding shaft (14, 35) rotatably supported adjacent a window edge (7), a first window shade strip (16, 38) having one end attached to said first winding shaft (14, 35) and a free edge (37, 39) that can be moved away from the first winding shall (14, 35), a second winding shalt (14, 35) rotatably supported adjacent to another window edge (7), a second window shade strip (16, 38) attached to said second winding shaft (14, 35) and having a free edge (17, 39) that can be moved away from the second winding shaft (14, 35), a single drive unit (19, 61) operatively coupled through actuating elements (22, 23, 48) to each of said window shade strips (16, 39) for moving said window shade strips (16, 38) in at least one direction in response to operation of the drive unit (19, 61), said drive unit (19) having an output shaft with two toothed wheels (22, 55) of different effective diameters, one of said toothed wheels being engaged with one of said actuating elements for moving said first window shade strip as an incident to operation of said single drive unit, and the other toothed wheel being engaged with the actuating element of the second window shade strip for moving the second window shade strip as an incident to operation of said single drive unit.
In an automobile having two windows sized and configured differently from each other, a window shade arrangement comprising a first winding shaft (14, 35) rotatably supported adjacent a window edge (7), a first window shade strip (16, 38) shaped to conform generally to a first one of said windows and having one end attached to said first winding shaft (14, 35) and a free edge (37, 39) that can be moved away from the first winding shaft (14, 35), a second winding shaft (14, 35) arranged at an angle of about 90° to the first winding shaft (14, 35) and rotatably supported adjacent to another window edge (7), a second window shade strip (16, 38) shaped to conform generally to a second of said windows and differently from said first window shade strip, said second window shade strip (16, 38) being attached to said second winding shaft (14, 35) and having a free edge (17, 39) that can be moved away from the second winding shaft (14, 35), and a single drive unit (19, 61) operatively coupled to each of said window shade strips (16, 39) for moving said window shade strips (16, 38) in at least one direction in response to operation of the drive unit (19,61) into respective overlying relation with said two windows.
