Seat belt

Claim 2

A buckle for guiding two belt runs, comprising a first passage for the first belt run to extend through said buckle, a second passage for the second belt run to extend through said buckle, the two passages meeting in a meeting region, the second passage having a width from side to side greater than its thickness from top to bottom and being provided with an opening adjacent to one side such that the second belt run can be introduced into the second passage without folding, the parts of the buckle which define the opening overlapping each other, and a lip being provided on the buckle adjacent and extending away from the opening to assist in the insertion of the second belt run.

Claim 3

A buckle according to claim 1, wherein the opening opens into the second passage from a direction inclined to the plane of the belt when running through the second passage.

Claim 4

A buckle according to claim 1, wherein the first passage comprises two apertures side by side in a base plate of the buckle.

Claim 5

A buckle according to claim 1, wherein the second passage is inclined between a base plate and a top plate and the top plate is preferably inclined at a small angle to the base plate such that the thickness of the second passage is greater adjacent the opening.

Claim 6

A buckle according to claim 4, wherein said lip is an extension of the base plate.

Claim 7

A buckle according to claim 1, wherein the opening is positioned such that, in use, the second belt is urged away from the opening when the second belt acts as a restraint.

Claim 8

A buckle for joining first and second seat belts to correctly position a shoulder belt across a person seated in a seat, the first seat belt having a fixed first end and a second end fixed to a retractor device, the first seat belt having a tongue intermediate the first and second ends and removably fixed to a fixed clip so that the first belt defines a waist belt extending across a waist of a person and the shoulder belt extending diagonally across the chest and shoulder of a person, the second belt extending vertically over a seat back, said buckle comprising: a top wall; first and second side walls extending transversely from opposite sides of said top wall; a first bottom wall cantilevered to said first side wall, a substantial portion of said bottom wall extending generally parallel to said top wall, a free end of said first bottom wall defining a lip extending away from said top wall, said first bottom wall including first and second apertures therein which are separated by a central bar, the second seat belt extending into said first aperture over said central bar and through said second aperture whereby said buckle is selectively positionable on the second seat belt; a second bottom wall cantilevered to said second side wall, said second bottom wall being shorter than said first bottom wall, a free end of said second bottom wall being spaced from and overlapping said lip so as to create an opening adjacent said second side wall intermediate both said free ends, said opening receiving the first seat belt sidewardly therethrough without folding the same; and a through space enclosed by said top, first bottom, second bottom, first side, and second side walls for slidably receiving the shoulder belt after it is inserted sidewardly without folding through said opening into said through space, said through space being wider between said side walls than between said top and first and second bottom walls, whereby the position of the shoulder belt can be adjusted by moving said buckle containing the first belt along the second belt.

Claim 9

A buckle for joining first and second seat belts to correctly position a shoulder belt across a person seated in a seat, the first seat belt having a fixed first end and a second end fixed to a retractor device, the first seat belt having a tongue intermediate the first and second ends and removably fixed to a fixed clip so that the first belt defines a waist belt extending across a waist of a person and the shoulder belt extending diagonally across the chest and shoulder of a person, the second belt extending vertically over a seat back, said buckle comprising: a top wall; first and second side walls extending transversely from opposite sides of said top wall; a first bottom wall cantilevered to said first side wall, a substantial portion of said bottom wall extending generally parallel to said top wall, a free end of said first bottom wall defining a lip extending away from said top wall, said first bottom wall including first and second apertures therein which are separated by a central bar, the second seat belt extending into said first aperture over said central bar and through said second aperture whereby said buckle is selectively positionable on the second seat belt; a second bottom wall cantilevered to said second side wall, said second bottom wall being shorter than said first bottom wall, a free end of said second bottom wall being spaced from and overlapping said lip so as to create an opening adjacent said second side wall intermediate both said free ends, said opening receiving the first seat belt sidewardly therethrough without folding the same; and a through space enclosed by said top, first bottom, second bottom, first side, and second side walls for slidably receiving the shoulder belt after it is inserted sidewardly without folding through said opening into said through space, said through space being wider between said side walls than between said top and first and second bottom walls, whereby the position of the shoulder belt can be adjusted by moving said buckle containing the first belt along the second belt.

Claim 10

A buckle according to claim 7, wherein said through space extends substantially perpendicular to said first and second apertures, said first and second apertures open into said through space so that the first and second belts extend in a same direction through the buckle, and the second belt as it passes over said central bar is directly adjacent a portion of the first belt extending in said through space.

Claim 11

A buckle according to claim 7, wherein said top wall is enlarged in a plane and a front edge of said top wall is arcuate.
