Description

TECHNICAL FIELD

The following disclosure relates generally to personal restraint systems for use in vehicles and, more particularly, to buckle assemblies having swivel features and dual release features.

BACKGROUND

There are many types of personal restraint systems for use in automobiles, aircraft, all-terrain-vehicles, and other vehicles. Such systems include, for example, seat belts for use by adults and children of sufficient size, and child seats with associated restraints for use by toddlers and small children.

One method of securing seat belts or webs around an occupant includes releasably attaching an end portion of each of the webs to a buckle assembly. The buckle assembly retains the webs around the occupant during use, and also enables the occupant to release or separate the webs after use. Conventional buckle assemblies can be positioned to the side of an occupant or in front of an occupant. For example, a “three point” harness system, as typically found in conventional automobiles, can include a shoulder web and a lap web that are releasably secured to a buckle assembly positioned proximate to the occupant's hip. A “five point’ harness system can include a crotch web, first and second shoulder webs, and first and second lap webs that are releasably secured to a buckle assembly positioned proximate to the occupant's mid-section.

DETAILED DESCRIPTION

The following disclosure describes buckle assemblies and associated web connectors for use with personal restraint systems in vehicles. As described in greater detail below, a personal restraint system configured in accordance with one aspect of the disclosure can include a buckle assembly with swiveling features and dual release features (e.g., separate release features for releasing one or more webs from the buckle assembly). Certain details are set forth in the following description and in FIGS. 1-10B to provide a thorough understanding of various embodiments of the disclosure. However, other details describing well-known structures and systems often associated with buckle assemblies, web connectors, and/or other aspects of personal restraint systems are not set forth below to avoid unnecessarily obscuring the description of various embodiments of the disclosure.

Many of the details, dimensions, angles, and other features shown in the Figures are merely illustrative of particular embodiments of the disclosure. Accordingly, other embodiments can have other details, dimensions, angles, and features without departing from the spirit or scope of the present disclosure. In addition, those of ordinary skill in the art will appreciate that further embodiments of the disclosure can be practiced without several of the details described below.

In the Figures, identical reference numbers identify identical or at least generally similar elements. To facilitate the discussion of any particular element, the most significant digit or digits of any reference number refers to the Figure in which that element is first introduced. For example, element 110 is first introduced and discussed with reference to FIG. 1.

FIG. 1 is an isometric view of a portion of a restraint system 10 configured in accordance with an embodiment of the disclosure. In the illustrated embodiment, the restraint system 10 includes a buckle assembly 100 that is operably coupled to multiple belts or webs. For example, the restraint system 10 includes a first web 102 coupled to the buckle assembly 100 with a swivel subassembly 104. The restraint system 10 also includes a second web 106 that can be releasably coupled to the buckle assembly 100 via a web connector 108. More specifically, the web connector 108 includes a web receiving portion 110 that receives the second web 106. In certain embodiments, the second web 106 can be fixedly attached to the web receiving portion 110. In other embodiments, however, the second web 106 can slidably pass through the web receiving portion 110. The first and second webs 102, 106 are configured to at least partially restrain an occupant in a vehicle.

As used herein, the term “webs” can refer to any type of flexible straps or belts, such as seat belts made from woven material known in the art for use with personal restraint systems. In certain embodiments, the webs described herein can include segments of a fixed length and/or adjustable length to accommodate different sized occupants. In a particular embodiment, the first web 102 and/or the second web 106 can be static webs. In other embodiments, however, the distal ends of the webs can be operably coupled to one or more retractors (e.g., inertial reels) to provide adjustable lengths of the webs. In addition, one of ordinary skill in the art will appreciate that the restraint system can be used with any type of vehicle including, for example, automobiles, military vehicles, aircraft, rotorcraft, watercraft, racing vehicles, etc. Moreover, the buckle assemblies described herein can be used with any type of restraint system, including, for example, personal restraints, automobile restraints, aircraft restraints, racing restraints, child restraints, parachute restraints, fall-protection restraints, aviation tie down restraints, etc. In addition, although the embodiment illustrated in FIG. 1 includes a single first web 102 coupled to the swivel sub-assembly 104 and/or a single second web 106 coupled to the web connector 108, in other embodiments multiple webs can be coupled to the swivel sub-assembly 104 and/or the web connector 108.

According to one aspect of the illustrated embodiment, and as described in detail below, the swivel subassembly 104 can be securely attached to the first web 102 and be configured to freely rotate with reference to the buckle assembly 100. As such, the swivel subassembly 104 prevents or inhibits the first web 102 and/or the second web 106 from twisting.

According to yet another aspect of the illustrated embodiment, and as described in detail below, the buckle assembly 100 includes multiple quick release mechanisms or features for detaching the connection between the buckle assembly 100 and the web connector 108. For example, the web connector 108 includes a tongue 112 with a corresponding locking feature or pawl aperture 114. When a user inserts the tongue 112 into an opening 116 in the buckle assembly 100, the buckle assembly 100 lockably engages the pawl aperture 114 of the tongue 112. To release the tongue 112 from the buckle assembly 100, a user can selectively actuate at least one of a first release actuator or button 120 and a second release actuator pull or pin 124. As described in detail below, a user can depress the release button 120 into the buckle assembly 100 to release the tongue 112. Moreover, the user can also pull the second release actuator 124 away from the buckle assembly 100 to release the tongue 112. For example, the user can grab a gripping feature or pull tab 128 that is coupled to the second release actuator 124. In the illustrated embodiment the pull tab 128 is coupled to the second release actuator 124 via a connecting ring 126. In other embodiments, however, the buckle assembly 100 can include other suitable mechanisms for providing a convenient grip or access to the second release actuator 124.

FIG. 2A is a partially exploded isometric view, FIG. 2B is a partially exploded side view, FIG. 2C is an exploded isometric view, and FIG. 2D is an exploded side view of the of the buckle assembly 100 of FIG. 1. Referring to FIGS. 2A-2D together, in one aspect of this embodiment the buckle assembly 100 includes a housing or cover 229 that generally encloses the internal components of the buckle assembly 100. The cover 229 can include a first or top cover 231a opposite a second or bottom cover 231b. The first cover 231a and the second cover 231b can include several locating features or openings for securely locating and/or coupling to one another as well as the corresponding features of the buckle assembly 100.

According to another aspect of the illustrated embodiment, the buckle assembly 100 also includes a support structure or frame 230 positioned inside the cover 229 and coupled to several of the other corresponding components of the buckle assembly 100. In the illustrated embodiment, the frame 230 includes a tongue opening 236 (FIGS. 2C and 2D) configured to removably receive the web connector tongue 112 (FIG. 1). The frame 230 also includes a base portion 232 (FIGS. 2C and 2D) that is slidably coupled to the first release actuator or button 120. The base portion 232 is also configured to secure or engage an alignment guide 240 on the frame 230. The base portion 232 further includes a locking member channel or opening 234 (FIG. 2C) that movably receives a pawl or locking feature or member 250 (FIGS. 2B-2C). The locking member 250 is configured to slidably move at least partially within the alignment guide 240 and the locking member opening 234 in the frame 230.

According to another aspect of the embodiment illustrated in FIGS. 2A-2D, the buckle assembly 100 includes a spring or biasing member 260 configured to bias or urge the locking member 250 toward a locked position (FIG. 2B) relative to the frame 230. More specifically, the biasing member 260 includes a first end portion 261 that is coupled to the locking member 250, and a second end portion 262 opposite the first end portion 261. The second end portion 262 is coupled to the release button 120. The biasing member 260 is curved or otherwise configured to bias or push the locking member 250 toward the locked position. In certain embodiments, the biasing member 260 can be made from a metallic material, such as spring steel. In other embodiments, however, the biasing member 260 can be made from other suitable biasing materials. As explained in detail below, when the release button 120 is actuated (via a first release mechanism or a second release mechanism), the release button 120 moves the locking member 250 against the biasing member 260 and out of the locked position to disengage the web connector tongue 112 (FIG. 1).

In another aspect of the illustrated embodiment, the release button 120 includes an opening 221 (FIG. 2C) extending therethrough and at least partially defining an interior surface of the release button 120. The release button 120 at least partially receives the alignment guide 240, the locking member 250, and the biasing member 260 in the opening 221. The release button 120 also includes a slanted or angled release pin contact surface 222 (FIGS. 2A and 2C) at least partially defined by the opening 221. The release pin contact surface 222 is configured to contact a corresponding release pin 264 to actuate or move the release button 120. With reference to FIGS. 2C and 2D, the release pin 264 includes a first end portion 265 that slides along the release pin contact surface 222. The release pin 264 also includes a second end portion 266 opposite the first end portion 265 that is coupled to the second release actuator 124. More specifically, the second release actuator 124 includes a first end portion 270 with a release pin opening 271 that receives the second end portion 266 of the release pin 264. The second release actuator 124 also includes a second end portion 268 opposite the first end portion 270 that is accessible outside of the cover 229. Accordingly, the second end portion 268 is easily accessible for a user to pull and actuate the release button 120 to move the release pin 264 along the release pin contact surface 222 of the release button 120.

According to yet another aspect of the illustrated embodiment, the buckle assembly 100 further includes a support block 272 that is secured to the frame 230 with multiple fasteners 233 (e.g., bolts, screws, rivets, pins, posts, etc., and identified individually as a first fastener 233a and a second fastener 233b). More specifically, the fasteners 233 extend through corresponding frame fastener openings 238 (identified individually as a first frame fastener opening 238a and a second frame fastener opening 238b) and corresponding support block fastener openings 273 (identified individually as a first support block fastener opening 273a and a second support block fastener opening 273b). The support block 272 also includes a release actuator opening 275 (FIGS. 2C and 2D) that slidably receives the second release actuator 124, as well as a release pin slot 274 (FIG. 2C) that slidably receives the release pin 264. The release pin slot 274 has a generally oblong or oval shape and extends partially into the support block 272 to intersect the release actuator opening 275. Accordingly, the first end portion 265 of the release pin 264 can slidably move through the release pin slot 274 as the second release actuator 124 slidably moves through the release actuator opening 275 in the support block 272.

In another aspect of the illustrated embodiment, the swivel subassembly 104 is coupled to the support block 272. More specifically, the swivel subassembly 104 includes a swivel fastener 277 (e.g., a bolt, shoulder bolt, screw, etc.) that coupled a swivel web connector 280 (e.g., a looped connector or eye nut). The swivel fastener 277 includes a first end portion 276 opposite a second end portion 278 carrying a flange or head portion 279. The first end portion 276 of the swivel fastener 277 is secured in the support block 272, and the second end portion 278 is received in a swivel fastener opening 282 (FIG. 2C) of the swivel web connector 280. A base portion 281 of the swivel web connector 280 is therefore rotatably secured between the support block 272 and the head portion 279 of the swivel fastener 277. As such, the swivel web connector 280 can freely rotate with reference to the frame 230.

Further details regarding the components of the buckle assembly are described in detail below with reference to FIGS. 3A-7D.

The alignment projections 339 are configured to contact or engage corresponding alignment grooves in the locking member 250 (see, e.g., FIGS. 5A-5C).

According to another aspect of the illustrated embodiment, at the first end portion 331a the first base-half 333a is spaced apart form the second base-half 333b to allow the tongue portion 112 of the web connector 108 (FIG. 1) to fit therein. As also shown in the illustrated embodiment, the first end portion 331a includes multiple engaging recesses 337 (identified individually as a first engaging recess 337a and a second engaging recess 337b) partially extending through each of the first base-half 333a and the second base-half 333b. The engaging recesses 337 are configured to contact or engage corresponding projections from the alignment guide 240. As also shown in the illustrated embodiment, at the second end portion 331b of the frame 230, the first base-half 333a is posited adjacent to and contacts the second base-half 333b. The second end portion 331b also includes the frame fastener openings 238 that are configured to receive the corresponding support block fasteners 233 for attachment to the support block 272 (FIG. 2C).

FIGS. 4A and 4B are isometric views, FIG. 4C is a side view, and FIG. 4D is a top view of the alignment guide 240 of the buckle assembly 100 of FIGS. 2A-2D. Referring to FIGS. 4A-4D together, the alignment guide 240 includes a first arm 442a spaced apart from a second arm 442b. Each arm 442 includes a corresponding biasing extension 444 (identified individually as a first biasing extension 444a and a second biasing extension 444b) extending therefrom. Each arm 442 also includes an alignment extension 443 (identified individually as a first alignment extension 443a and a second alignment extension 443b) projecting from a lower surface 441 of the alignment guide 240. The lower surface 443 is configured to rest against the first base-half 333 of the frame 230 in the buckle assembly 100 (see, e.g., FIGS. 2A-2D). The alignment extensions 443 are configured to contact or engage the corresponding engaging recesses 337 of the first end portion 331a of the frame 230 to retain the alignment guide 240 generally stationary with reference to the frame 230. The biasing extensions 444 are configured to contact an interior surface of the release button 120 to provide a biasing or resistive force against the release button 120 as the release button 120 moves along the frame 230 between the locked and unlocked positions.

According to another feature of the embodiment shown in FIGS. 4A-4D, the alignment guide 240 includes a locking member guide channel 445 and a biasing member channel 447 formed between two locking member stepped guide arms 446 (identified individually as a first stepped guide arm 446a and a second stepped guide arm 446b). The locking member guide channel 445 is sized and shaped to receive the locking member 250 (FIGS. 2A-2D) and allow the locking member 250 to move within the alignment guide 240 between the locked and unlocked positions. The biasing member channel 447 is configured to allow for the movement of the biasing member 260 through the alignment guide 240 as the locking member 250 moves between the locked and unlocked positions.

FIGS. 5A-5C are isometric views and FIG. 5D is a side view of a movable pawl or locking member 250 of the buckle assembly 100 of FIGS. 2A-2D. Referring to FIGS. 5A-5D together, the locking member 250 is configured to be positioned within the pawl aperture 114 of the tongue 112 to lock the web connector 108 in the buckle assembly 100 (FIG. 1). For example, the locking member 250 includes a first locking surface 551 that is configured to contact or engage an interior surface of the tongue 112 in the pawl aperture 114. The locking member 250 also includes a first ramped surface 557 that is configured to contact the tongue 112 only after the locking member 250 has been at least partially moved out of the locked position. As such, the tongue 112 can contact the ramped surface 557 to urge or at least partially help to move the locking member 250 toward the unlocked position. The locking member 250 also includes alignment grooves or channels 559 (identified individually as a first alignment channel 559a and a second alignment channel 559b) that are configured to at least partially receiving the corresponding alignment projections 339 in the alignment opening 234 of the frame 230 (FIGS. 3A-3D). The alignment channels 559 are configured to guide or align the locking member 250 with reference to the frame 230 as the locking member 250 moves between the locked and unlocked positions.

According to another aspect of the illustrated embodiment, the locking member 250 also includes locking extensions or arms 552 (identified individually as a first locking arm 552a opposite a second locking arm 552b). Each locking arm 552 includes multiple surfaces that are configured to engage or contact the release button 120 (FIGS. 2A-2D) to retain the locking member 250 in a locked position and to move the locking member 250 into the unlocked position. More specifically, each locking arm 552 includes a first or resting surface 553 opposite a second or lock surface 554. Each locking arm 552 also includes a third or sliding surface 555 extending at an inclined angle from the first or resting surface 553. The resting surfaces 553, the lock surfaces 554, and the sliding surfaces 555 are each configured to contact or otherwise interact with the release button 120 as the release button 120 moves the locking member 250 between the locked and unlocked positions. The contact or engagement of these surfaces with the release button 120 are described in detail below with reference to FIGS. 7A and 7B.

FIGS. 6A and 6B are isometric views, FIG. 6C is a top view, and FIG. 6D is a side cross-sectional view taken substantially along line 6D-6D of FIG. 6C of the first actuator or release button 120 of the buckle assembly 100 of FIGS. 2A-2D. Referring to FIGS. 6A-6D together, the release button 120 includes a middle portion 623 between a first end portion 621 and a second end portion 625. The first end portion 621 can include an exterior surface 619 that is configured to be externally accessible for a user to push or depress to move or actuate the release button 120.

According to another aspect of the illustrated embodiment, the middle portion 623 includes several features that are configured to engage or otherwise contact the locking member 250 to move the locking member 250 between the locked and unlocked positions. For example, in the middle portion 623 the release button 120 includes sidewalls 626 (identified individually as a first sidewall 626a spaced apart from a second sidewall 626b) extending longitudinally along the release button 120. Each sidewall 626 includes a release feature or release protrusion 627 spaced apart from a locking feature or locking protrusion 631. In certain embodiments, the release protrusion 627 and the locking protrusion 631 are integrally formed in the corresponding sidewall 626. In other embodiments, however, the release protrusion 627 and the locking protrusion 631 can be separate components that are attached to the corresponding sidewall 626. Each release protrusion 627 includes a first or unlocking surface 628 extending from a second or resting surface 629. The unlocking surface can be a ramped surface extending (e.g., extending upwardly) from the resting surface 629 at an inclined angle. Each locking protrusion 631 includes a third or locking surface 635 that is spaced apart from and generally parallel to the resting surface 629. The contact or engagement of these surfaces of the release button 120 with the locking member 250 is described in detail below with reference to FIGS. 7A and 7B.

According to yet another aspect of the embodiment illustrated in FIGS. 6A-6D, the second end portion 625 includes an opening 641 extending therethrough. The opening 641 at least partially defines the release pin contact surface 222 of the second end portion 625. The release pin contact surface 222 extends at an inclined angle relative to a longitudinal axis of the release button 120. Further details regarding the interaction of the release pin contact surface 222 and the release pin 264 are described in detail below with reference to FIGS. 7C and 7D.

FIGS. 7A and 7B are cross-sectional partial side views taken substantially along line 7-7 of FIG. 2A, and FIGS. 7C and 7D are top partial views illustrating various operational aspects of the buckle assembly 100 and corresponding components illustrated in FIGS. 1-6D. In FIGS. 7A-7D, the cover 229 and swivel sub-assembly 104 are removed from the buckle assembly 100 to illustrate several of the internal features of the buckle assembly 100. Moreover, in FIGS. 7A and 7B, the alignment guide 240 is also removed to illustrate several of the features of the release button 120 and the locking member 250. Referring first to FIG. 7A, for example, the buckle assembly 100 is illustrated in a locked position. With the locking member 250 in the locked position with reference to the frame 230 and the release button 120, the locking member 250 is positioned to engage or retain a tongue from a web connector locked in the buckle assembly 100. More specifically, in the locked position the resting surface 553 and the sliding surface 555 of the locking arm 552 of the locking member 250 contact or rest against the resting surface 629 and the unlocking ramped surface 628, respectively, of the release button 120. At this point, the top locking surface 554 of the locking arm 552 is positioned adjacent to (e.g., below) the corresponding locking surface 635 of the locking protrusion 631. Accordingly, in the locked position, the locking protrusion 631 of the release button 120 at least partially prevents the locking member 250 from moving in an unlocking direction D₁ relative to the frame 230 (e.g., in a direction generally perpendicular to a longitudinal axis L of the buckle assembly 100).

Referring next to FIG. 7B, when an operator moves the release button 120 in a second direction D₂ relative to the frame 230 (e.g., in a direction generally parallel to the longitudinal axis L of the buckle assembly 100), the release button 120 moves the locking member 250 to an unlocked position (e.g., to a position in which the locking member 250 allows a corresponding tongue of a web connector to be withdrawn from the buckle assembly 100). In one embodiment, the user can actuate the release button 120 by pressing the exterior surface 619 to move the release button 120 in the second direction D₂. As explained in detail below, however, the user can also actuate the release button via the release pin 264. As shown in FIG. 7B, as the release button 120 moves in the second direction D₂, the ramped unlocking surface 628 of the release button 120 contacts the sliding surface 555 of the locking arm 552. Accordingly, the release button 120 slides or drives the locking member 250 along the unlocking surface 628 to move the locking member 250 in the unlocking direction D₁ relative to the frame 230 (i.e., in a direction generally perpendicular to a longitudinal axis of the buckle assembly 100). At this point, the locking surface 554 of the locking arm 552 is spaced apart from and has cleared the locking surface 635 of the locking protrusion 631.

Referring next to FIG. 7C, the buckle assembly 100 is illustrated again in the locked position. As shown in the illustrated embodiment, the release pin 264 extends from the second actuator 124 through the release pin slot 274. In the locked position, the release pin 264 contacts the release pin contact surface 222 of the release button 120 at a first lateral side portion 705 of the release button 120. Referring next to FIG. 7D, which illustrates the buckle assembly 100 in the unlocked position, when a user has pulled the second release actuator 124 in a third direction D₃ (i.e., in a direction generally perpendicular to a longitudinal axis of the buckle assembly 100), the release pin 264 slides along the release pin contact surface 222 along a fourth direction D₄ at an inclined angle relative to a longitudinal axis of the buckle assembly 100. As the release pin 264 moves perpendicularly to the longitudinal axis of the buckle assembly 100 and along the fourth direction D₄ on the release pin contact surface 222, the release pin 264 drives or urges the release button 120 to the unlocked position, and the release button 120 in turn moves the locking member 250 to the unlocked position.

According to yet another feature of the embodiment illustrated in FIG. 7D, the swivel subassembly 104 allows the swivel web connector 280 to rotate in directions R (e.g., rotation about a longitudinal axis of the buckle assembly 100). Accordingly, the swivel subassembly 104 prevents a web 102 (FIG. 1) that is attached to the swivel web connector 280 from twisting or becoming misaligned during use.

In the illustrated embodiment, the release connector 883 includes a connector stop 884 at a distal end portion thereof that is configured to contact and pull the release button 820 when a user pulls the release connector 883. More specifically, when a user pulls the release connector 883 in a second direction D₂, which is generally perpendicular to the first direction D₁ and the longitudinal axis L of the buckle assembly 800, the connector stop 884 pulls the release button 820 to the unlocked position. In other embodiments, however, the release connector 883 can extend or be pulled at angles other than perpendicular to the longitudinal axis L of the buckle assembly 800.

In certain embodiments, the buckle assembly 800 can also include a second release connector stop 885 and a biasing member 886 (e.g., a coil spring) positioned between a first wall 887a and a corresponding second wall 887b. In an unlocked position, the biasing member 886 can push against the second wall 887b to urge the second connector release stop 885 toward the first wall 887a so that the first release connector stop 884 is spaced apart from or otherwise disengaged from the release button 820. To move the release button 820 to the unlocked position, a user can pull or otherwise actuate the release connector 883, which in turn compresses the biasing member 886 via the second release connector stop 885 until the first release connector stop 884 contacts and moves the release button 820 in the first direction D₁.

The blade 1094 includes a sharpened cutting portion or edge 1095 that is configured to allow a user to easily cut through a web (not shown) coupled to the buckle assembly 1000. For example, in the illustrated embodiment, the cutting portion 1095 has a curved or generally U-shaped configuration that allows a user to hook the web to pull and cut through the web. Accordingly, the embodiment illustrated in FIGS. 10 and 10B allows a user to cut the buckle assembly 1000 from a corresponding web in an emergency or other situation when a user is unable to otherwise disengage the web from the buckle assembly 1000.

The embodiments of the buckle assemblies including dual release features provide several advantages over conventional buckle assemblies. One advantage, for example, is that a buckle assembly of the present disclosure eliminates the need for the buckle assembly to be oriented so that the first actuator or release button is visible or accessible. Instead, a user can easily locate and pull the second actuator pin from any orientation of the buckle assembly. Moreover, the secondary release mechanism that can be pulled relative to the buckle assembly to release the buckle assembly eliminates the need to provide any opposing force on the buckle assembly when actuating the primary push release button. For example, a user can easily pull the secondary release actuator with one hand, thereby leaving the user's other hand free for other tasks. Moreover the swivel subassemblies described herein also prevent twisting or misalignment of the corresponding webs.

From the foregoing, it will be appreciated that specific embodiments of the disclosure have been described herein for purposes of illustration, but that various modifications may be made without deviating from the spirit and scope of the various embodiments of the disclosure. Further, while various advantages associated with certain embodiments of the disclosure have been described above in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the invention.
