Problems solved by technology
Although it has been found that in a rollover accident or if the vehicle is hit from the side, the additional shoulder belts do a better job of keeping the vehicle occupant in his / her seat, but many users consider the additional two-point seat to be safer. uncomfortable
Furthermore, when encouraging occupants to use seat belt systems including three-point seat belts and two-point seat belts, it has proven difficult to justify the need to fasten additional seat belts
In addition, if the two-point seat belt is installed on the backrest of the vehicle passenger seat, the cost can be expensive because the vehicle passenger seat may need to be reinforced or modified to withstand the force exerted by the two-point seat belt. force

Embodiment Construction
[0025] figure 1 and figure 2 A seat belt system 10 for a vehicle (such as a passenger car) according to an embodiment of the present invention is shown from the front and side, respectively. The seat belt system 10 includes a three-point seat belt 12 having a first portion 12 a disposed diagonally across the chest of a vehicle occupant 14 and a second portion 12 b disposed across the pelvis of the vehicle occupant 14 . The seat belt system 10 also includes a looser fitting two-point seat belt 16 disposed diagonally across the first portion 12a of the three-point seat belt 12 An X-shaped "criss-cross" seat belt is formed across the chest of a vehicle occupant 14 . Thus, in the event of a crash, the three-point seat belt 12 is configured to absorb more force than the two-point seat belt 16 .
[0026]The seat belt system 10 includes a first storage device 18 mounted, for example, on a pillar (not shown) of the vehicle, such as a B-pillar or a C-pillar (depending on the seat),...

Seat belt system (10) for a vehicle including: a 3-point seat belt (12) that comprises a first section (12a) that is arranged to diagonally cross the chest of a vehicle occupant (14) and a second section (12b) that is arranged to cross the pelvis of a vehicle occupant (14), and a 2-point seat belt (16) that is arranged to diagonally cross the chest of a vehicle occupant (14) in a direction that crosses said first section (12a) of said 3-point seat belt (12) so as to form an X-shape. The seat belt system (10) also comprises a first locking means (24) that is arranged to lock said 2-point seat belt (16) when the force on said 2-point seat belt (16) exceeds a predetermined first force (F1), and a first force limiter (29) that is arranged to substantially maintain the force exerted by the 2-point seat belt (16) on the vehicle occupant (14) at said predetermined first force (F1). The seat belt system (10) also comprises a second locking means (26) that is arranged to lock said 3-point seat belt (12) when the force on said 3-point seat belt (F) exceeds a predetermined second force (F2), and a second force limiter (27) that is arranged to substantially maintain the force exerted by the 3-point seat belt (12) on the vehicle occupant (14) at said predetermined second force on the seat belt (F2). The predetermined first force (F1) is less than the predetermined second force (F2).
Description
technical field [0001] The present invention relates to a seat belt system, and a vehicle having such a seat belt system.
