VEHICLE SIDE COLLISION OCCUPANT RESTRAINT SYSTEM

Abstract

A safety restraint system for a vehicle that includes seat belts that extend over both side pelvic portions and both side rib cage portions of the vehicle occupant and directly prevents inward and outward lateral displacement of the side pelvic portions and side rib cage portions during a side collision event. Said side belts attach to a forward-facing seat belt system with two shoulder belts, one on either side of the neck, for improved performance on the torso in a collision event, and a lap belt, while still maintaining the convenience of a single buckle click task for the occupant to secure the belt system.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0014] FIG. 1 provides a front view of the aspects of the present invention that incorporate the integration of a lateral restraining system comprising two pairs of side restraining belts integrated with a conventional seat belt restraint system comprising a pair of shoulder belts affixed to a center-buckle lap belt system.

DETAILED DESCRIPTION

[0015] In general, the fundamental function of interior restraints is to keep an occupant away from the structure or other occupants of a vehicle and to absorb forces on the occupant's body during a collision event. The present invention provides such restraint and absorption, which is described in detail below.

[0016] The present invention may also be applied in automobile and non-automobile applications.

[0017] In the following description, various operating parameters and components are described for one constructed embodiment. These specific parameters and components are included as examples and are not meant to be limiting.

[0018] Also, in the following description the term “performing” may include activating, deploying, initiating, powering, and other actions known in the art that may describe the manner in which a countermeasure may be operated.

[0019] Additionally, in the following description the term “countermeasure” may refer to an object or may refer to an action. For example, a countermeasure may be performed or a countermeasure may be activated. An airbag is a countermeasure. A controller may perform a countermeasure by signaling the airbag to deploy.

[0020] Moreover, a countermeasure device may be any device within an automotive vehicle that is used in conjunction with a collision countermeasure system including: a controller, a vehicle system, an indicator, or other countermeasure device known in the art.

[0021] In addition, the term “collision type”' refers to collision severity and collision contact location of a collision. Collision type may include whether a collision is a frontal-oblique, side, offset, or head-on collision, as well as refer to other collision location type descriptions known in the art. A collision type may also include information related to relative size, weight, and collision change-in-velocity, as well as other collision type related information known in the art.

[0022] Referring now to FIG. 1, a front view of a lateral restraining system incorporating side seat belts in accordance with an embodiment of the present invention is shown. The lateral restraining system prevents lateral displacement of vehicle occupants 1 during a collision event. The term “lateral displacement” refers to a horizontal direction perpendicular to and away from a longitudinal centerline of the vehicle.

[0023] The lateral system may include multiple additional seat belts with side belts and accompanying retractors, D-rings, buckles and corresponding receivers, and anchors. The seat belts may also have corresponding pretensioners and pyrotechnic devices, which may be located within or coupled to the retractors and the receivers. The side belts may be inflatable. The seat belts, the retractors, the D-rings, the buckles, the receivers, the pretensioners and pyrotechnic devices may all be of various types and styles and be in various configurations. The seat belts reside over the occupants and the seats. Some of the retractors, D-rings, and anchors may be coupled to the seat frames or to the vehicle chassis, as desired.

[0024] A controller may be coupled to collision sensors, retractors, the buckle 3, the receiver, and to the side belts, as well as to various pretensioners and pyrotechnic devices associated therewith. The controller may activate and control the operation of the stated items during a collision event. The pretensioners and pyrotechnic devices may include solenoids and electric motors. The pretensioners pull in on the associated seat belts to take up any slack in the belts and prevent the belts from extending during a collision event.

[0025] The lap belts 4 are coupled between lap belt anchors 9 and the buckle 3. The lap belt anchors 9 are located on the sides of the seat structure 2 or coupled to the vehicle chassis directly. The lap belts 4 extend from the lap belt anchors 9 across a pelvis of the occupant 1 to the buckle 3.

[0026] The shoulder belts 6 are coupled between shoulder belt anchors 8 and the lap belts 4 or buckle 3. The shoulder belt anchors 8 are located behind the occupant's shoulders on the vehicle chassis (e.g. harness bar) or to the seat structure 2 if designed and sized for seat belt forces. The shoulder belts 6 extend from the shoulder belt anchors 8 over the shoulders of the occupant 1, down the chest and abdomen to the lap belts 4 or buckle 3.

[0027] The lap side belts 5 may be coupled in various locations onto the lap belts 4 or buckle 3, including integrally stitched into or with the lap belts 4, as shown, or may be coupled via a clasp (not shown) or may be fastened, adhered, or attached using some other method known in the art. The second ends of the lap side belts 5 are coupled to a side lap belt anchor point or retractor or to the lap belt anchor point 9 on the other side of the seat such that the lap side belts wrap behind and around the sides of the pelvis to provide immediate lateral restraint during a collision event. The coupling method is such to withstand loading during a collision event. The lap side belt anchor points or retractors are located a distance away from the structures meant to be avoided by the restraint of the belt in a collision and are further from those structures laterally than the side of the pelvis itself. The lap side belt anchor point or retractor may be located in the seat structure 2 or vehicle chassis.

[0028] The rib cage side belts 7 may be coupled in various locations onto the shoulder belts 6 or buckle 3, including integrally stitched into or with the shoulder belts 6, as shown, or may be coupled via a clasp (not shown) or may be fastened, adhered, or attached using some other method known in the art. The second ends of the rib cage side belts 7 are coupled to a rib cage side belt anchor point or retractor or to the shoulder belt anchor 8 on the opposite side of the seat such that the rib cage side belts wrap around the sides of and then extend behind the rib cage to provide immediate lateral restraint during a collision event. The coupling method is such to withstand loading during a collision event. The rib cage side belt anchor points or retractors are located a distance away from the structures meant to be avoided by the restraint of the belt in a collision and are further from those structures laterally than the side of the rib cage itself. The rib cage side belt anchor point or retractor may be located in the seat structure 2, if designed and sized for seat belt forces, or vehicle chassis (e.g. harness bar).

[0029] The present invention is a vehicle safety system that provides lateral restraining systems that may be used to further prevent injury-causing contact between a vehicle occupant and vehicle structures and other occupants during a side collision event. The present invention further prevents loads from being exerted on and bodily deflections experienced by a vehicle occupant. Thus, the present invention provides an improved safety restraint system that further prevents injury to a vehicle occupant during a side collision event.

[0030] While the invention has been described in connection with one or more embodiments, it is to be understood that the specific mechanisms and techniques which have been described are merely illustrative of the principles of the invention, numerous modifications may be made to the methods and apparatus described without departing from the spirit and scope of the invention as defined by the appended claims.
