Sunshades for vehicle windows are provided, including a shade having upper and lower edges, and a pair of support members having free ends. One of the members is associated with each of the upper and lower edges, and the support members are constructed to be spaced apart to support the shade in an extended, open position during use. Each of the support members includes a self-straightening tape that is arcuate in cross-section and can be repeatedly folded without significant plastic deformation.

Sunshades for vehicle windows are provided, including a shade having upper and lower edges, and a pair of support members having free ends. One of the members is associated with each of the upper and lower edges, and the support members are constructed to be spaced apart to support the shade in an extended, open position during use.

Seat underframe according to claim 1, in which the abutment face of the release cam is connected by a rounded portion to the cam surface of the release cam, and the actuating member is urged elastically towards the first position by at least one spring which is powerful enough that when the free end of the first branch of the release finger comes into contact with the rounded portion in the absence of external actuation of the actuating member, the spring urging the actuating member drives the actuating member with the release cam into the first position and brings the cam surface of the release cam into contact with the first branch of the release finger. 3. Seat underframe according to claim 1, in which the second branch of the release finger extends at an angle in the longitudinal direction and downwards at least when the release finger is in the active position. 4. Underframe according to claim 1, in which the framework of the underframe comprises two horizontal sliding shoes oriented downwards and intended to bear on a sliding surface belonging to the rail, the free end of the second branch of the release finger projecting downwards beyond the sliding shoes when the release finger is in the active position, between the sliding shoes. 5. Seat underframe according to claim 1, in which the release cam is integral with an abutment zone against which the first branch of the release finger angularly abuts when the release finger is in the active position. 6. Seat underframe according to claim 1, in which the release cam is integral with the actuating member, which is mounted to pivot about a first axis of rotation parallel to the transverse direction. 7. Seat underframe according to claim 6, in which the release cam is integral with a pivot cam which collaborates with a first cam follower integral with the catch, the pivot cam being designed to press against the first cam follower by causing the catch to pivot about a pivot axle parallel to the longitudinal direction, from the locked position to the retracted position when the actuating member passes from the first position to the second position, the catch being urged in the opposite direction by a catch spring. 8. Seat underframe according to claim 7, in which the first cam follower of the catch has an upper bearing surface against which the pivot cam bears to cause the catch to pivot, the upper bearing surface being laterally offset with respect to the rotation axle of the catch. 9. Seat underframe according to claim 7, in which the actuating member is secured to a locking cam and the catch is mounted to pivot on the framework of the underframe with a certain vertical play, between the locked position and a sliding position situated below the locked position, the locking cam coming to bear under a second cam follower situated towards the upper end of the body of the catch so as to hold the catch in the locked position as long as the actuating member is in an angular position lying between the first position and a third position intermediate between the first and second positions, and the locking cam being designed to allow the catch to drop into the sliding position when the actuating member is in an angular position lying between the third and second positions. 10. Seat underframe according to claim 9, in which the locking cam is in the form of a rigid platelet stretching in a vertical plane roughly parallel to the body of the catch, the locking cam comprisin g a slot in which there is engaged a peg integral with the catch, the slot being shaped to press against the peg and cause the catch to drop into the sliding position when the actuating member is in the third position. 11. Seat underframe according to claim 9, in which the second cam follower of the catch comprises a rim stretching downwards, the locking cam penetrating between the rim and the body of the catch at least when the catch is in the locked position. 12. Seat underframe according to claim 9, in which the locking cam is in contact with the rim of the second cam follower, without clearance, when the catch is in the locked position. 13. Seat underframe according to claim 12, in which the rim of the second cam follower and the locking cam are shaped to collaborate with one another via a cam effect so as to cause the catch to pivot from the retracted position into the sliding position when the actuating member pivots from the second angular position to the third angular position. 14. Seat underframe according to claim 13, in which the locking cam has a chamfer which collaborates with an angled interior face belonging to the rim of the second cam follower so as to move the catch from the retracted position to the sliding position when the actuating member pivots from the second angular position to the third angular position. 15. Seat underframe according to claim 9, in which the actuating member comprises a metal shaft which is integral with the locking cam, the release cam and pivot cam being integral with a hollow shaft which is fitted over the metal shaft and which is not connected in terms of rotation directly to the metal shaft, the hollow shaft having end tabs which collaborate by fitting-together with a first operating member that can be actuated by a user, immobilizing the hollow shaft in terms of rotation with respect to the first operating member, the first operating member having a notched hole into which a free end belonging to the metal shaft penetrates, the free end being crimped into the notched hole, thereby securing the first operating member to the metal shaft. 16. Seat underframe according to claim 9, in which the actuating member is integral with a first operating member that can be actuated by a user, which allows the actuating member to be moved between the first and second positions, the actuating member also being mechanically connected to a pinion which is in mesh with a ring of teeth secured to a second operating member that can be actuated by a user, the second operating member being movable in rotation about a second axis of rotation parallel to the first axis of rotation between a rest position and an abutment position corresponding respectively to the first and third positions of the actuating member, the second operating member coming into contact with an abutment integral with the framework of the underframe when the second actuating member is in the abutment position, and the pinion being connected, with a certain amount of backlash, to the actuating member, so that the actuating member can pivot from the third to the second position in a first angular direction while the second operating member remains bearing against the corresponding abutment integral with the framework of the underframe. 17. Seat underframe according to claim 16, in which the pinion is urged elastically in the first angular direction so as normally to be kept bearing angularly against an abutment integral with the actuating member. 18. Seat underframe according to claim 1, in which the claw of the catch has a free end provided with teeth which project upwards and which are aligned in the longitudinal direction. 19. Seat underframe according to claim 18, in which there are at least three teeth on the catch, the claw of the catch stretching between a front end and a rear end, and the teeth of the claw having heights which decrease from the front end towards the rear end of the claw. 20. Seat underframe according to claim
