Abstract
Description
Technical Field
[0001] The subject disclosure relates to the field of occupant restraint systems for vehicles, and more particularly to adjustable occupant restraint system supports for vehicles. Background Art
[0002] Many passenger cars, especially those manufactured after 1968, are equipped with passenger restraint systems. Initially, vehicles were equipped with lap belts. In some cases, an additional, separate shoulder belt may also be provided. The use of lap belts has been shown to reduce deceleration injuries. As vehicle seating systems have evolved, improvements in restraint systems have also begun to appear. A combined lap belt and shoulder belt including a retractor that responds to deceleration forces has been developed and incorporated into the vehicle. The combined lap belt and shoulder belt further reduces deceleration injuries.
[0003] In addition to passive restraint systems (such as lap and shoulder belts), supplementary restraint systems (such as airbags) have been added as additional safety systems for seated passengers. Although passive and supplementary restraint systems have been shown to be effective in protecting seated passengers, they are not as effective for reclined passengers.
[0004] In a reclined position, the shoulder belt may be out of position, such as hovering above the passenger. A shoulder belt out of position in this manner may allow the passenger to move too far forward during a sudden deceleration. Thus, there remains a need to protect passengers who may be in a reclined position. It would therefore be desirable to provide a system that can adjust the restraint configuration to accommodate not only seated passengers in an upright position, but also passengers who may be in a reclined, highly reclined, or sleeping position.

[0033] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application or use. It should be understood that throughout the drawings, corresponding reference numerals represent identical or corresponding components and features. As used herein, the term module refers to a processing circuit, which may include an application specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated or group) and memory that executes one or more software or firmware programs, a combinational logic circuit, and / or other suitable components that provide the described functionality.
[0034] According to a non-limiting example, the vehicle Figure 1 The vehicle 10 is generally indicated at 10. The vehicle 10 includes a body 12 supported on a plurality of wheels 16. The body 12 partially defines a passenger compartment 20 having a plurality of structural supports 24. The structural supports 24 include "A" pillars 26, "B" pillars 28, and C pillars 30. Additional structural supports are also present (not separately labeled). The structural supports 24 extend between a passenger compartment floor 32 and a roof 33. A plurality of seats are arranged in the passenger compartment 20, one of which is indicated at 34. The seats 34 may include outer seats (e.g., seats arranged near, for example, a door) and intermediate seats (e.g., seats disposed between the outer seats).
[0035] according to Figure 2 and Figure 3In the non-limiting example shown, the seat 34 includes a seat base 38 including a leg support 40 and a seat back 42 including a headrest 46. The seat back 42 is pivotally connected to the seat base 38. The seat base 38 includes a seating surface 48, and the seat back 42 includes a support surface 56 having a first end 58 pivotally connected to the seat base 38 and a second end 60 supporting the headrest 46. As will be described in detail herein, the seat back 42 can be positioned about the first end 58 in a first or upright position ( Figure 2 ) and a second or highly tilted position ( Figure 5 In this regard, it should be understood that the highly reclined position describes a state in which the seat back 42 is tilted more than 35° from the vertical and the seat base 38 can be pivoted upward more than 20° from the horizontal and the leg support 40 is raised and extended outward from the seat base 38.
[0036] A passenger restraint system, shown in the form of a seat belt 64, is disposed proximate the seat 34. The seat belt 64 includes a first end portion 68 fixedly mounted to, for example, a "C" pillar 30, a second end portion 70 connected to the seat base 38, and a middle portion 72. The middle portion 72 extends between the first end portion 68 and the second end portion 70. In a non-limiting example, the first end portion 68 includes a retractor 74 coupled to the "C" pillar 30. A buckle 78 is slidably supported on the middle portion 72. The buckle 78 is selectively connected to a belt release 80 disposed adjacent the seat 34. In a non-limiting example, the middle portion 72 passes through an adjustable passenger restraint system support 82, shown in the form of a belt guide 84 disposed adjacent the second end 60 of the seat back 42.
[0037] In a non-limiting example, the seat belt guide 84 is connected to a seat belt guide system 90 that is mounted to, for example, the "C" pillar 30, such as Figure 1 As will be described in more detail herein, the seat belt guide system 90 includes a guide mechanism 94 that causes the seat belt guide 84 to move in a forward position ( Figure 2 ) and the backward position ( Figure 5 ) between. Figure 6 , the guide mechanism 94 includes a guide rail 98 having a first end section 102, a second end section 104, and an intermediate section 106 extending between the first end section 102 and the second end section 104. The guide rail 98 is shown as being substantially linear. However, it should be understood that the shape of the guide rail can vary. A shuttle 112 connected to the seat belt guide 84 is displaced between the first end section 102 and the second end section 104.
[0038] In a non-limiting example, the shuttle 112 is supported by a lead screw 116 having a plurality of threads 118. The lead screw 116 is connected to an actuator, which may take the form of an electric motor 130. The electric motor 130 rotates the lead screw 116 to displace the shuttle 112 between the first end section 102 and the second end section 104. In this regard, while a lead screw driven by an electric motor is shown to move the shuttle, a variety of mechanisms may be employed to displace the guide member when the seat back 42 is displaced between the upright configuration and the highly reclined configuration.
[0039] Continue to refer Figure 6 , the seat belt guiding system 90 is connected to a controller 140 having a central processing unit (CPU) 142, a non-volatile memory module 144, and a shuttle control module 146. The controller 140 receives signals from a seat actuator 148 and a first limit switch 154, a second limit switch 156, and a seat position sensor 160 mounted to the seat 34. In operation, a user can select to move the seat 34 from a closed position to a closed position by engaging the seat actuator 148. Figure 2 The upright structure shifted to Figure 5 At this time, a signal can be transmitted from the seat actuator 148 to the controller 140 indicating that the seat back 42 is moving. When the seat back 42 stops moving, the controller 140 receives a signal from the seat position sensor 160 indicating that the seat back 42 is in a highly reclined position.
[0040] The controller 140 signals the shuttle control module 146 to displace the shuttle 112 from the first end section 102 of the guide rail 98 toward the second end section 104. The movement of the shuttle 112 is constrained by the first limit switch 154 and the second limit switch 156. The shuttle 112 then moves the seat belt guide 84 from the first position ( Figure 4 ) to the second position ( Figure 5 ). In the second position, the seat belt 64 is repositioned closer to the resting occupant to limit deviation from the seat 34 during sudden deceleration. When the seat 34 returns to the upright position, the belt guide system 90 moves the shuttle 112 and the belt guide 84 rearward toward the first end section 102.
[0041] In a non-limiting example, the belt guide system 90 can reposition the belt guide 84 between the first end section 102 and the second end section 104 based on the seat angle. The shuttle position 112 can be adjusted based on the seat angle sensed by the seat position sensor 160 or based on user preferences stored in the non-volatile memory module 144. Thus, in a non-limiting example, the belt guide system 90 operates to maintain the seat belt 64 in a selected position to limit excursion from the seat 34 during sudden deceleration, regardless of the seat back angle.
