Abstract
Abstract Safety belt installation designed to enable a vehicle user to accede to and leave his seat easily and to ensure that the user is necessarily wearing his safety belt when he is seated, no catch or buckle being required. The installation further enables integration with a seat independently of the vehicle concerned, hence facilitating construction and fitting on a production line of vehicles with seats provided with safety belts. The installation comprises a safety belt properly speaking, one section of which is fed from a device for reeling and unreeling a strap constituting the belt and is such that the belt is guided by two arms pivotably mounted about an axis located in the upper portion of the seat, so that the belt, which is anchored at its extremities to three fixed points on the seat and/or vehicle, is suitable for being brought from its non-operational position, wherein at least one section extends above the back of the seat, to a state wherein it is applied against the occupant of the seat after pivoting of said guide arms.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
202 words
Three point safety belt installation particularly for an occupant of a vehicle having a floor and a seat with a seat back, comprising a seat belt, either end thereof being fixedly anchored to respective one of two vertically spaced structural portions of the vehicle on one side of the seat, a common strap, one end thereof being secured to an intermediate portion of said seat belt and the other end thereof being connected to a belt retractor secured to the floor on the other side of the seat, a transverse shaft rotatably mounted in an upper portion of the seat back, a pair of arms movable from a first position wherein said seat belt engages the occupant of the vehicle to a second position wherein said seat belt is removed from the occupant for easy ingress and egress to and from the seat, each of said arms being non-rotatably connected at one end thereof to a respective end of said shaft and having an aperture provided at the other thereof, each said aperture slidably engaging respective one of said common strap and said seat belt, actuating means operatively connected to said shaft for rotating said arms between said first and second position.
Claim 2
Dependent Claim

Three point safety belt installation particularly for an occupant of a vehicle having a floor and a seat with a seat back, comprising a seat belt, either end thereof being fixedly anchored to respective one of two vertically spaced structural portions of the vehicle on one side of the seat, a common strap, one end thereof being secured to an intermediate portion of said seat belt and the other end thereof being connected to a belt retractor secured to the floor on the other side of the seat, a transverse shaft rotatably mounted in an upper portion of the seat back, a pair of arms movable from a first position wherein said seat belt engages the occupant of the vehicle to a second position wherein said seat belt is removed from the occupant for easy ingress and egress to and from the seat, each of said arms being non-rotatably connected at one end thereof to a respective end of said shaft and having an aperture provided at the other thereof, each said aperture slidably engaging respective one of said common strap and said seat belt, actuating means operatively connected to said shaft for rotating said arms between said first and second position.
Claim 3
Dependent Claim
17 words
Safety belt installation according to claim 1, wherein each guide arm comprises at least two inter-articulated sections.
Claim 4
Dependent Claim
20 words
Safety belt installation according to claim 2, wherein the relative movement of the inter-articulated sections is actuated by camming means.
Claim 5
Dependent Claim
45 words
Safety belt installation according to claim 3, wherein one extremity of a cam follower housed in the inter-articulated section rotatably integral with said shaft cooperates with the camming means which is fixed, the other extremity of the cam follower abutting with the other inter-articulated section.
Claim 6
Dependent Claim
55 words
Safety belt installation according to claim 3, wherein the camming means cause the guide arms to adopt their shortest length position when the belt is in said second position, anD cause said guide arms to assume their greatest length position during their pivoting movement which brings the belt from second position to said first position.
Claim 7
Dependent Claim
60 words
Safety belt installation according to claim 5, wherein when the belt is in said first position, the guide arms are also in their shortest length position, one of the inter-articulated sections extending substantially parallel to the lateral edges of the back of the vehicle seat and the other inter-articulated section substantially parallel to the bearing surface of the vehicle seat.
Claim 8
Dependent Claim
30 words
Safety belt installation according to claim 2, wherein the inter-articulated sections are relatively displaced by rod means, elastic torsion means being provided between the inter-articulated sections of each guide arm.
Claim 9
Dependent Claim
71 words
Installation according to claim 7, wherein said elastic torsion means are constituted by a coil spring attached to each of the sections of the arm and housed about a spacer means disposed between the two sections and which surrounds their articulation pin, said coil spring whose force is greater than said second of the reel return means being armed in the state wherein the arms maintain the belt in non-operational position.
Claim 10
Dependent Claim
69 words
Safety belt installation according to claim 7, wherein the rod means connected to each of the guide arms is articulated at one extremity to a fixed support integral with the means for mounting the guide arm on the vehicle seat and at its other extremity articulated on the section of the guide arm which is not rotatably integral with the pivoting control shaft controlling pivoting of said guide arm.
