Abstract
Abstract A device for adjusting a strap of a safety belt for vehicles and like craft comprises a latch in the form of a bar which is transversely movable with respect to a base plate. The base plate is formed with an opening through which the strap is passed about the bar for clamping the strap between the bar and the base plate when the strap is subjected to pull. At a heavy pull at the strap, the bar is adapted to be shifted laterally of the opening in the direction of pull. Between the base plate and the bar the device has a thin flat member which is associated with the base plate and adapted, at a heavy pull at the strap, to be carried along by the bar when the latter is shifted laterally of the opening. At said shifting movement the flat member lies between the strap and the base plate so that the strap is protected against abrasion under the heavy load.

Claim 1
Independent Claim
226 words
A device for adjusting a strap of a safety belt for vehicles and like craft, said device being a latch in the form of a bar which is transversely movable with respect to a base plate formed with an opening which is associated with the bar and through which the strap is passed about the bar for clamping the strap between the bar and the base plate when the strap is subjected to pull, said bar being adapted, at a heavy pull at the strap, to be shifted laterally of the opening in the direction of pull, wherein the belt strap adjusting device has between the base plate and the bar a thin flat member which is associated with the base plate and adapted, at a heavy pull at the strap, to be carried along by the bar when the latter is shifted laterally of the opening, said flat member lying at said shifting movement between the strap and the base plate so that the strap is protected against abrasion under the heavy load, said flat member being a metal sheet having a bent edge portion which is adapted to grasp the edge of the opening cooperating with the strap, said bent edge portion being disposed to be straightened when the flat metal sheet member is carried along by the bar in the shifting movement thereof.
Claim 2
Independent Claim

A device for adjusting a strap of a safety belt for vehicles and like craft, said device being a latch in the form of a bar which is transversely movable with respect to a base plate formed with an opening which is associated with the bar and through which the strap is passed about the bar for clamping the strap between the bar and the base plate when the strap is subjected to pull, said bar being adapted, at a heavy pull at the strap, to be shifted laterally of the opening in the direction of pull, wherein the belt strap adjusting device has between the base plate and the bar a thin flat member which is associated with the base plate and adapted, at a heavy pull at the strap, to be carried along by the bar when the latter is shifted laterally of the opening, said flat member lying at said shifting movement between the strap and the base plate so that the strap is protected against abrasion under the heavy load, said flat member being a metal sheet having a bent edge portion which is adapted to grasp the edge of the opening cooperating with the strap, said bent edge portion being disposed to be straightened when the flat metal sheet member is carried along by the bar in the shifting movement thereof.
Claim 3
Dependent Claim
70 words
A belt strap adjusting device as claimed in claim 1, wherein the flat member is formed, at the edges extending in the longitudinal direction of the strap, with upwardly directed embossed portions, which at a heavy pull at the strap are adapted to be deformed by projections arranged at the ends of the bar, whereby the projections will carry the flat member along in the shifting movement of the bar.
Claim 4
Dependent Claim
35 words
A belt strap adjusting device as claimed in claim 2, wherein the upwardly directed embossed portions of the flat member are in the form of ribs which extend throughout the edges of said flat member.
Claim 5
Dependent Claim
34 words
A belt strap adjusting device as claimed in claim 1, wherein the flat member is adapted, in combination with a protective cover for the bar, to cooperate with the two sides of the strap.
