1. A sunvisor with for a vehicle, comprising
a sunvisor body comprising a front surface and a rear surface; a hinging arrangement for hinging the sunvisor body to a roof structure of a vehicle body such that the sunvisor body is tiltable about an upper horizontal axis between a first screening position where said front surface faces an upper portion of a windshield and an inoperative position where said rear surface is upwardly folded to face the roof structure, the hinging arrangement comprising a hook member located above an upper side portion of the sunvisor body and in which a rod-shaped lateral extension of the sunvisor body is detachably engaged when the sunvisor is in the first screening position and in said inoperative position, an upper rod unrotatably connected to the sunvisor body and comprising a lateral end portion that laterally protrudes from a side portion of the sunvisor body which is opposite to said rod-shaped lateral extension, and a detent member rotatably coupled to the upper rod and designed to selectively retain the sunvisor body in at least said first screening position and in said inoperative position; pivot means connected to the lateral end portion of the upper rod and fastened to the roof structure to swing the sunvisor body against a resistance exerted against pivoting by a braking arrangement, between the first screening position where the sunvisor body is hooked in the hook member to a second screening position where the rear surface of the sunvisor body is adjacent to an upper portion of a side window; wherein the detent member is coupled to the lateral end portion of the rod and located outside the sunvisor body, and the pivot means are integrated in the detent member, and wherein: the lateral end portion of the rod comprises an engagement portion; the detent member comprises a detent clip comprising an enveloping portion and two wing portions emerging from the enveloping portion, and a housing with an inner hollow for accommodating the detent clip; the enveloping portion tightly embraces a peripheral portion of the engagement portion; the housing is pivotally coupled to a foot member that is fixedly fastenable to the roof structure; the housing comprises two axially-opposed throughholes for rotatably bearing the engagement portion, and retaining means to which the wing portions of the detent clip are coupled; the engagement portion and the enveloping portion are rotatably coupled to each other in such a manner that a friction torque is opposed against rotation of the rod when the sunvisor body is tilted between said first screening position and said inoperative position; the foot member comprises a base plate with a circular opening and a cylindrical upper body portion comprising a cylindrical hollow which is aligned with the circular opening to form a cylindrical passage; at least an upper portion of the housing has a cylindrical shape dimensioned to fit snugly and pivotally within said cylindrical passage; the housing comprises an upper base provided with at least two clipping members which are slidably retained on an upper rim portion of the cylindrical upper body portion of the foot member; and said braking arrangement comprises a spiral spring member, with two edges tightly fixed to the foot member and wound around a peripheral portion of the cylindrical upper body portion of the foot member, such that a friction torque between the detent member and the spiral spring member must be overcome to pivot the sunvisor body from said first screening position to said second screening position. |
