Abstract

Abstract A safety belt system comprises a belt strap at which locally an energy absorption member is provided which is formed by a belt strap section which is folded together at least once and is sewn together. So that the occupant of the seat or the repair shop, even after a minor accident, is informed as to whether the safety belt system must be exchanged, a marking is mounted at the belt strap adjacent to the energy absorption member in such a manner that, when the energy absorption system is intact, the marking is invisible to the occupant of the seat or the repair shop, whereas when the seam is at least partially ripped open, the marking is within view.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 139 words
A safety belt system, particularly for motor vehicles, having a belt strap at which locally an energy absorption member is provided which is formed by a belt strap section which is folded together at least once and is sewn together, the energy absorption member extending inside a belt strap covering, wherein a marking is provided at the belt strap adjacent to the energy absorption member in such a manner that the marking is invisible to an external observer of the seat when the energy absorption member is intact and that the marking is visible to an external observer when the seam of the energy absorption member is at least partially ripped, whereby external observers, such as a vehicle occupant or vehicle repair shop personnel, can detect the condition of the belt strap section without removing the belt strap covering.
Claim 2
Dependent Claim 139 words
A safety belt system, particularly for motor vehicles, having a belt strap at which locally an energy absorption member is provided which is formed by a belt strap section which is folded together at least once and is sewn together, the energy absorption member extending inside a belt strap covering, wherein a marking is provided at the belt strap adjacent to the energy absorption member in such a manner that the marking is invisible to an external observer of the seat when the energy absorption member is intact and that the marking is visible to an external observer when the seam of the energy absorption member is at least partially ripped, whereby external observers, such as a vehicle occupant or vehicle repair shop personnel, can detect the condition of the belt strap section without removing the belt strap covering.
Claim 3
Dependent Claim 30 words
A safety belt system according to claim 1, wherein the marking for the belt strap is arranged inside the envelope-type belt strap covering when the energy absorption member is intact.
Claim 4
Dependent Claim 29 words
A safety belt system according to claim 1, wherein the marking extends adjacent to the upper opening of the belt strap covering when the energy absorption member is intact.
Claim 5
Dependent Claim 59 words
A safety belt system according to claim 1, wherein the marking arrives outside the belt strap covering and thus is visible to the vehicle occupant or to the repair shop even as a result of the partial ripping-open of the seam and thus by means of a slight lengthening of the belt strap, when the safety belt is worn.
Claim 6
Dependent Claim 24 words
A safety belt system according to claim 1, wherein the marking is formed by a color bar which is applied to the belt strap.
Claim 7
Dependent Claim 23 words
A safety belt system according to claim 1, wherein the marking is developed as a line of writing, a symbol or the like.
Claim 8
Independent Claim 143 words
A method of making a safety belt system, particularly for motor vehicles, having a belt strap at which locally an energy absorption member is provided which is formed by a belt strap section which is folded together at least once and is sewn together, the energy absorption member extending inside a belt strap covering, wherein a marking is provided at the belt strap adjacent to the energy absorption member in such a manner that the marking is invisible to an external observer of the seat when the energy absorption member is intact and that the marking is visible to an external observer when the seam of the energy absorption member is at least partially ripped, whereby external observers, such as a vehicle occupant or vehicle repair shop personnel, can detect the condition of the belt strap section without removing the belt strap covering.
Claim 9
Independent Claim 143 words
A method of making a safety belt system, particularly for motor vehicles, having a belt strap at which locally an energy absorption member is provided which is formed by a belt strap section which is folded together at least once and is sewn together, the energy absorption member extending inside a belt strap covering, wherein a marking is provided at the belt strap adjacent to the energy absorption member in such a manner that the marking is invisible to an external observer of the seat when the energy absorption member is intact and that the marking is visible to an external observer when the seam of the energy absorption member is at least partially ripped, whereby external observers, such as a vehicle occupant or vehicle repair shop personnel, can detect the condition of the belt strap section without removing the belt strap covering.
Claim 10
Dependent Claim 28 words
A method according to claim 7, wherein the marking for the belt strap is arranged inside the envelope-type belt strap covering when the energy absorption member is intact.
Claim 11
Dependent Claim 27 words
A method according to claim 7, wherein the marking extends adjacent to the upper opening of the belt strap covering when the energy absorption member is intact.
Claim 12
Dependent Claim 57 words
A method according to claim 7, wherein the marking arrives outside the belt strap covering and thus is visible to the vehicle occupant or to the repair shop even as a result of the partial ripping-open of the seam and thus by means of a slight lengthening of the belt strap, when the safety belt is worn.
Claim 13
Dependent Claim 22 words
A method according to claim 7, wherein the marking is formed by a color bar which is applied to the belt strap.
Claim 14
Dependent Claim 21 words
A method according to claim 7, wherein the marking is developed as a line of writing, a symbol or the like.
