Description
BACKGROUND OF THE INVENTION
Some vehicle accidents are inevitable; however, it is possible to reduce the chance of casualty due to 4 head injury, spine injury, neck injury, and chest injury. Upon an event of a side impact, the wounded occupants are likely to suffer from neck injury because the heads of the occupants are not secured.onto 6 the headrests to absorb the impact. For some vehicles equipped with side airbags, the heads of the occupants swing side ways, and then the occupants collide onto the deployed airbags, such safety 8 features might not be enough to prevent severe neck injury during a side impact. Upon an event of a roll-over, most convertible vehicles have a great chance of fatality. Although current active roll-over protection systems trigger protective bars to prevent the direct impact from ground to the occupants, the occupants are often taller than protective bars; therefore an evasive action is necessary. Protective bars 12 are incapable of preventing the occupants from hitting by flying debris during a roll-over; therefore a shielding mechanism is an asset. Upon an even of a front impact, most vehicles deploy front airbags 14 and project towards the occupants' faces. Such safety features prevent the occupants from directly hitting the front dash, however, the occupants might suffer from hearing impairs due to exploding 16 sound during the airbag deployment. Direct impact from the front airbag deployment on the occupants might cause facial, neck, and chest injury if the occupants are seating in an improper position or too 18 close towards the front dash; therefore a more reliable restrain and airbag system is desired. Upon an even of a rear impact, current impact protection system has developed to protect the occupants from injuring due to whiplash; however, the necks of the occupants are subject to swing in side directions, therefore an improved vehicle restraining system is desired.
22 Nevertheless, preventing accidents from happening is also crucial in addition to preventing injuries during accidents. Many people turn on the vehicle heater during winter. Heat and vapor inside the 24 vehicles often condense on windshield, which lowers the visibility of the road and increases the chance of accidents. Therefore a seatbelt warmer system is developed to co-act with the current seat warmer 26 system so that the occupants have less need to turn on the occupant compartment heater.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
To further clarify the configuration and the operation of the present invention as explained above, 4 obvious assembly components such as wires, screws and gears are simplified or omitted from the drawings.
The present invention comprising four main components: headrest assembly, seat assembly, seatbelt 8 assembly, and airbag system.
As shown in FIG.2 and FIG.3a, headrest assembly comprising: headrest frame 201, headrest padding 311, left flap frame 301, left padding 303, left hinge 305, left spring 307, left position lock 309, right 12 flap frame 302, right flap padding 304, right hinge 306, right spring 308, and right flap position lock 310.
As shown in FIG.10, seat assembly comprising: backrest frame 1001, backrest padding 1002, headrest 16 socket 1004, seat frame 1001, motor 1003, and seat wanner (not shown).
18 As shown in FIG.4, seatbelt assembly comprising: left hip belt 406, left shoulder belt 405, left buckle 409, right hip belt 407, right shoulder belt 408, right buckle 410, top left anchor 401, bottom left anchor 402, top right anchor 404, bottom right anchor 403, seatbelt warmer 901 (FIG.
9), left seatbelt retractor (not shown), right seatbelt retractor (not shown), left seatbelt pretensioner (not shown), and right 22 seatbelt pretensioner (not shown).
24 Airbag system comprising three main airbags: front airbag 801, side airbag (not shown), and shielding airbag 802, installed on seatbelt.
As shown in FIG.3a is headrest assembly. Left padding 303 and right padding 304 cover onto left flap 28 frame 301 and right flap frame 302 respectively. Left flap frame 301 and right flap frame 302 are attached to left hinge 305 and right hinge 306 respectively. Left hinge 305 and right hinge 306 are pivotally affixed to headrest frame 201. At initial position as shown in FIG2a, left spring 307 and right spring 308 are in-tension. Left flap consists of left flap frame 301 and left flap padding 303. Right flap 32 consists of right flap frame 302 and right flap padding 304. When the vehicle restraining system is activated during a collision as shown in FIG.2b, left position lock 309 and right position lock 310 2 release left flap and right flap respectively, left spring's tension and right spring's tension cause left flap and right flap to swing forward. After each deployment of the vehicle restraining system, left flap 4 and right flap can be restore to left position lock 309 and right position lock 310. The purpose of the vehicle restraining system is to reduce the chance of neck injury in the event of a collision.
As shown in FIG.10 is seat assembly. Backrest padding 1002 covers onto backrest frame 1001. Seat 8 warmer are installed inside backrest padding 1002 and seat padding. Motor 1003 is installed underneath seat frame 1006. Headrest socket 1004 provides an insertion point for headrest frame 201 to be secured onto backrest frame 1001.
12 Now referring to FIG.4 and FIG.9, a four-point seatbelt assembly is constructed as the drawing.
Seatbelt warmer 901 is embedded within left should belt 405, right should belt 408, left hip belt 406, 14 right hip belt 407. When seatbelt warmer 901 is activated, seatbelt warmer 901 heats up to keep occupant warm. Shielding airbag 802 is installed inside shielding airbag compartment 902. When 16 shielding airbag deploys, shielding airbag 802 expands and travels forward to collide with front airbag 801.
Seatbelt assembly can also be constructed in a three-point seatbelt configuration.
With the implementation of seatbelt warmer 901 and seat warmer, the occupant receives warmth 22 directly through skin contact, therefore, the occupant may occupy the vehicle with a lower air temperature. As the air temperature decreases, the amount of water vapor released from occupant's 24 respiratory decreases as well. Lower air temperature and lower humidity reduce the chance of window fogging; therefore, the chance of collision due to low visibility is also reduced.
The purpose of shielding airbag 802 is to absorb the impact from front airbag 801 in the event of a 28 collision, and shielding airbag 802 cannot be used without a front airbag during a frontal collision.
Shielding airbag 802 in a four-point seatbelt assembly is more stable and reliable comparing to shielding airbag in a three-point seatbelt assembly. Left buckle 409 and right buckle 410 of a four-point 32 seatbelt assembly are always engaged in the center abdomen position of the occupant, while buckle of a three-point seatbelt assembly does not always engaged in the same position.
Therefore, it is less 2 appealing to installed shielding airbag on a three-point seatbelt. However, seatbelt warmer 901 is a feature suitable for every form of seatbelts.
In order to protect the occupant in the event of a front impact, the following procedures are taken:
6 immediately after CPU sends signal to trigger the safety procedures for a front impact, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent 8 the occupant from neck injury by securing the occupant's head between left flap and right flap.
Shielding airbag 802 and front airbag 801 are then deployed at the same time.
As shown in FIG.8 Shielding airbag 802 travels in the occupant's forward direction and collides with front airbag 801. The collision between shielding airbag 802 and front airbag 801 prevent front airbag 801 from impacting 12 occupant's head with high velocity, thus minimizing the impact force and the chance of neck injury.
The sound from deployment of front airbag 801 and shielding airbag 802 is also muffled due to the fact 14 that the occupant's ears have been covered by left flap and right flap.
This action prevents occupants from hearing damage.
In order to protect the occupant in the event of a side impact, the following procedures are taken:
18 immediately after CPU sends signal to trigger the safety procedures for a side impact, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent the occupant from neck injury by securing the occupant's head between left flap and right flap. Side airbag is deployed to prevent the occupant from cutting by shattered glass or any flying objects.
In order to protect the occupant in the event of a rear impact, the following procedures are taken:
24 immediately after CPU sends signal to trigger the safety procedures for a rear impact, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent 26 the occupant from neck injury by securing the occupant's head between left flap and right flap.
28 As shown in FIG.6, in order to protect the occupant in the event of a roll-over, the following procedures are taken: immediately after CPU sends signal to trigger the safety procedures for a roll-over, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent the occupant from neck injury by securing the occupant's head between left flap 32 and right flap. Next, backrest frame 1001 backrest padding 1002, driven by motor 1003, then leans backward with the occupant secured onto backrest padding 1002 and headrest padding 311. Shielding 2 airbag 802 then deploys to prevent debris or flying objects from hitting the occupant as shown in FIG.7.

Motor 1003 is installed underneath seat frame 1006. Headrest socket 1004 provides an insertion point for headrest frame 201 to be secured onto backrest frame 1001.
12 Now referring to FIG.4 and FIG.9, a four-point seatbelt assembly is constructed as the drawing.
Seatbelt warmer 901 is embedded within left should belt 405, right should belt 408, left hip belt 406, 14 right hip belt 407. When seatbelt warmer 901 is activated, seatbelt warmer 901 heats up to keep occupant warm. Shielding airbag 802 is installed inside shielding airbag compartment 902. When 16 shielding airbag deploys, shielding airbag 802 expands and travels forward to collide with front airbag 801.
Seatbelt assembly can also be constructed in a three-point seatbelt configuration.
With the implementation of seatbelt warmer 901 and seat warmer, the occupant receives warmth 22 directly through skin contact, therefore, the occupant may occupy the vehicle with a lower air temperature. As the air temperature decreases, the amount of water vapor released from occupant's 24 respiratory decreases as well. Lower air temperature and lower humidity reduce the chance of window fogging; therefore, the chance of collision due to low visibility is also reduced.
The purpose of shielding airbag 802 is to absorb the impact from front airbag 801 in the event of a 28 collision, and shielding airbag 802 cannot be used without a front airbag during a frontal collision.
Shielding airbag 802 in a four-point seatbelt assembly is more stable and reliable comparing to shielding airbag in a three-point seatbelt assembly. Left buckle 409 and right buckle 410 of a four-point 32 seatbelt assembly are always engaged in the center abdomen position of the occupant, while buckle of a three-point seatbelt assembly does not always engaged in the same position.
Therefore, it is less 2 appealing to installed shielding airbag on a three-point seatbelt. However, seatbelt warmer 901 is a feature suitable for every form of seatbelts.
In order to protect the occupant in the event of a front impact, the following procedures are taken:
6 immediately after CPU sends signal to trigger the safety procedures for a front impact, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent 8 the occupant from neck injury by securing the occupant's head between left flap and right flap.
Shielding airbag 802 and front airbag 801 are then deployed at the same time.
As shown in FIG.8 Shielding airbag 802 travels in the occupant's forward direction and collides with front airbag 801. The collision between shielding airbag 802 and front airbag 801 prevent front airbag 801 from impacting 12 occupant's head with high velocity, thus minimizing the impact force and the chance of neck injury.
The sound from deployment of front airbag 801 and shielding airbag 802 is also muffled due to the fact 14 that the occupant's ears have been covered by left flap and right flap.
This action prevents occupants from hearing damage.
In order to protect the occupant in the event of a side impact, the following procedures are taken:
18 immediately after CPU sends signal to trigger the safety procedures for a side impact, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent the occupant from neck injury by securing the occupant's head between left flap and right flap. Side airbag is deployed to prevent the occupant from cutting by shattered glass or any flying objects.
In order to protect the occupant in the event of a rear impact, the following procedures are taken:
24 immediately after CPU sends signal to trigger the safety procedures for a rear impact, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent 26 the occupant from neck injury by securing the occupant's head between left flap and right flap.
28 As shown in FIG.6, in order to protect the occupant in the event of a roll-over, the following procedures are taken: immediately after CPU sends signal to trigger the safety procedures for a roll-over, pretensioner pulls the occupant onto backrest padding 1002, the vehicle restraining system is deployed to prevent the occupant from neck injury by securing the occupant's head between left flap 32 and right flap. Next, backrest frame 1001 backrest padding 1002, driven by motor 1003, then leans backward with the occupant secured onto backrest padding 1002 and headrest padding 311. Shielding 2 airbag 802 then deploys to prevent debris or flying objects from hitting the occupant as shown in FIG.7.
4 It should be understood that the invention is not limited to the embodiment described above.
Modifications and variations of the embodiment described above will occur to those skilled in the art 6 without leaving the spirit and scoop of the present invention. However the scope of the invention is defined with reference to the following claims.
