Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
68 words
A retention mechanism for the passengers of vehicles having seats provided with a seat cushion and a backrest, wherein the retention mechanism yields upon reaching a predetermined load, including means for transmitting the yielding movement of the retention mechanism onto the associated backrest independently of the seat cushion so as to move the backrest in a direction opposite to the movement of the passenger associated with that backrest.
Claim 2
Dependent Claim
68 words
A retention mechanism for the passengers of vehicles having seats provided with a seat cushion and a backrest, wherein the retention mechanism yields upon reaching a predetermined load, including means for transmitting the yielding movement of the retention mechanism onto the associated backrest independently of the seat cushion so as to move the backrest in a direction opposite to the movement of the passenger associated with that backrest.
Claim 3
Dependent Claim
16 words
A retention mechanism according to claim 1, characterized in that the vehicle is a motor vehicle.
Claim 4
Dependent Claim
23 words
A retention mechanism according to claim 1, characterized in that the retention mechanism yields in the load direction upon reaching the predetermined load.
Claim 5
Dependent Claim
26 words
A retention mechanism according to claim 3, characterized in that the retention mechanism yields in the load direction upon reaching a predetermined load under energy absorption.
Claim 6
Dependent Claim
61 words
A retention mechanism according to claim 4, wherein the yielding movement transmittal means includes a safety belt system with a belt portion adapted to be pulled out in case of a load, characterized in that the belt portion adapted to be pulled out in case of a load is secured at the lower leg of a tiltably arranged backrest fitting means.
Claim 7
Dependent Claim
33 words
A retention mechanism according to claim 5, characterized in that the fastening of said belt portion at the lower leg portion takes place by a connecting means provided with an intentional breaking place.
Claim 8
Dependent Claim
74 words
A retention mechanism according to claim 6, with a seat frame means having a lateral upright leg portion, characterized in that a detent means is provided at the lateral upright leg portion of the seat frame means within the pivot area of the lower leg portion of the backrest fitting means, and a pawl which projects elastically from the lower leg portion of the backrest fitting means, operable to engage into said detent means.
Claim 9
Dependent Claim
46 words
A retention mechanism according to claim 7, characterized in that the belt portion adapted to be pulled out is supported by a bolt secured at the seat frame means, said bolt tearing open the belt portion under energy absorption when a predetermined belt force is exceeded.
Claim 10
Dependent Claim
34 words
A retention mechanism according to claim 8, characterized in that the belt portion adapted to be pulled out is guided through a slot in the lateral upright leg portion of the seat frame means.
Claim 11
Dependent Claim
61 words
A retention mechanism according to claim 1, wherein the yielding movement transmittal means includes a safety belt system with a belt portion adapted to be pulled out in case of a load, characterized in that the belt portion adapted to be pulled out in case of a load is secured at the lower leg of a tiltably arranged backrest fitting means.
Claim 12
Dependent Claim
33 words
A retention mechanism according to claim 10, characterized in that the fastening of said belt portion at the lower leg portion takes place by a connecting means provided with an intentional breaking place.
Claim 13
Dependent Claim
74 words
A retention mechanism according to claim 10, with a seat frame means having a lateral upright leg portion, characterized in that a detent means is provided at the lateral upright leg portion of the seat frame means within the pivot area of the lower leg portion of the backrest fitting means, and a pawl which projects elastically from the lower leg portion of the backrest fitting means, operable to engage into said detent means.
Claim 14
Dependent Claim
46 words
A retention mechanism according to claim 12, characterized in that the belt portion adapted to be pulled out is supported by a bolt secured at the seat frame means, said bolt tearing open the belt portion under energy absorption when a predetermined belt force is exceeded.
Claim 15
Dependent Claim
34 words
A retention mechanism according to claim 12, characterized in that the belt portion adapted to be pulled out is guided through a slot in the lateral upright leg portion of the seat frame means.
