These and other aspects, objects, and features of the present disclosure will be understood and appreciated by those skilled in the art upon studying the following specification, claims, and appended drawings.
The following is a description of the figures in the accompanying drawings. The figures are not necessarily to scale, and certain features and certain views of the figures may be shown exaggerated in scale or in schematic in the interest of clarity and conciseness.
In the drawings:
Additional features and advantages of the presently disclosed device will be set forth in the detailed description which follows and will be apparent to those skilled in the art from the description, or recognized by practicing the device as described in the following description, together with the claims and appended drawings.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the concepts as oriented in
As used herein, the term “and/or,” when used in a list of two or more items, means that any one of the listed items can be employed by itself, or any combination of two or more of the listed items, can be employed. For example, if a composition is described as containing components A, B, and/or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.
As used herein, the term “about” means that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. When the term “about” is used in describing a value or an end-point of a range, the disclosure should be understood to include the specific value or end-point referred to. Whether or not a numerical value or end-point of a range in the specification recites “about,” the numerical value or end-point of a range is intended to include two embodiments: one modified by “about,” and one not modified by “about.” It will be further understood that the end-points of each of the ranges are significant both in relation to the other end-point, and independently of the other end-point.
As used herein the terms “the,” “a,” or “an,” mean “at least one,” and should not be limited to “only one” unless explicitly indicated to the contrary. Thus, for example, reference to “a component” includes embodiments having two or more such components unless the context clearly indicates otherwise.
In this document, relational terms, such as first and second, top and bottom, and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises ... a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

Referring to
The vehicle body 14 includes vertical supports, generally referred to as pillars 60. In the illustrated example, the pillars 60 include an A-pillar 62, a B-pillar 64, and a C-pillar 66. The first seating row 54 is generally disposed between the A-pillar 62 and the B-pillar 64, while the second seating row 56 is generally disposed between the B-pillar 64 and the C-pillar 66. Additional or fewer pillars 60 may be included in the vehicle 12 without departing from the teachings herein.
The vehicle 12 is illustrated as a truck; however, the vehicle 12 may be a sedan, a sport utility vehicle, a crossover, and other wheeled motor vehicles 12, or other types of vehicle 12. The vehicle 12 may be a manually operated vehicle 12 (e.g., operated with a human driver), a fully autonomous vehicle 12 (e.g., operated without a human driver), or a partially autonomous vehicle 12 (e.g., operated with or without a human driver). Additionally, the vehicle 12 may be utilized for personal and/or commercial purposes, such as, for ride-providing services (e.g., chauffeuring), transporting, and/or ride-sharing services.

In the example illustrated in
The air curtain assembly 20 generally includes the inflator 22 and an air curtain 72. The inflator 22 and the air curtain 72 are generally in fluid communication with one another. When the inflator 22 is activated, the air curtain 72 may generally be deployed by the inflator 22. The inflator 22 is generally disposed within the cavity 18 between the headliner 16 and the vehicle body 14. Typically, a sensor is configured to sense the predefined force, which results in the activation of the inflator 22.
The inflator bracket 24 is disposed between the inflator 22 and the vehicle body 14. The inflator bracket 24 may reduce or eliminate squeak-and-rattle caused by the air curtain assembly 20. The inflator bracket 24 maintains pressure between the inflator 22, the inflator bracket 24, and the vehicle body 14 to prevent rattle. Additionally, the inflator bracket 24 may generally maintain a space between the inflator 22 and the vehicle body 14.
The absorption feature 28 prevents free movement of the inflator bracket 24 relative to the vehicle body 14 (e.g., a support structure). Without the absorption feature 28, the inflator bracket 24 could move a select distance to reach the vehicle body 14. The absorption feature 28 generally has a height relative to the elongate body 26 that is substantially similar to the select distance to reduce or eliminate movement of the inflator bracket 24. Further, the inflator bracket 24 may absorb energy without substantially impinging space in the passenger cabin 50.
Referring to
A hook 88 extends from the second end 82 of the elongate body 26. The hook 88 generally extends substantially perpendicular to the elongate body 26. The hook 88 extends outward from the elongate body 26 and couples with the vehicle body 14. The hook 88 is configured to assist in retaining the space between the inflator bracket 24 and the vehicle body 14.
Referring still to
The absorption feature 28 may be disposed proximate to the hook 88 and proximate to the side arms 100, 102. The width of the elongate body 26 may be greater proximate to the side arms 100, 102. Additionally, the width of the elongate body 26 may decrease between the absorption feature 28 and the hook 88.
The first end 80 may be offset from the remainder of the elongate body 26. Accordingly, the elongate body 26 has an offset portion 104 at the first end 80, which is offset from the remainder of the elongate body 26 via a sloped portion 106. The offset portion 104 may provide additional space for the inflator 22 or other components of the air curtain assembly 20. The shape of the inflator 22 may change proximate to the first end 80 of the inflator bracket 24, and the inflator bracket 24 may include the offset portion 104 to continue to extend along the surface of the inflator 22.
The inflator bracket 24 may be coupled with the inflator 22 via first support features 120. The first support features 120 are generally bands that extend around the inflator 22 and the inflator bracket 24. In the illustrated example, the air curtain assembly 20 includes two support features 120 extending proximate to the side arms 100, 102 and a third support feature 120 extending proximate to the sloped portion 106. The first support features 120 generally operate to couple the inflator bracket 24 to the inflator 22 and retain the position of the inflator bracket 24 relative to the inflator 22.
Additionally or alternatively, the air curtain assembly 20 includes additional or second support features 122 that extend around the inflator bracket 24, the inflator 22, and the air curtain 72. The additional support features 122 are configured as bands that couple the various components of air curtain assembly 20 together.

The absorption feature 28 defines a radius or curve 150 in a center 152 between the proximal and distal ends 130, 132. The curve 150 is convex relative to the outer surface 134 of the elongate body 26 with an apex of the curve 150 disposed proximate to the vehicle body 14. An arc of the curve 150 defines a first radius when the absorption feature 28 is in the initial position 30. In this way, the absorption feature 28 extends away from the outer surface 134 of the elongate body 26, defines the curve 150 over the aperture 136, and extends toward the outer surface 134, while remaining spaced from the outer surface 134 at the distal end 132. The absorption feature 28 may define a generally parabolic shape, a generally sinusoidal shape, or any other practicable shape that defines at least one curve 150.

The deceleration increases as the absorption feature 28 bends at the junction 160. The rate of deceleration then decreases to a vertex 178. The vertex 178 coincides with the distal end 132 engaging the outer surface 134 of the elongate body 26.
The second peak 176 of deceleration coincides with the second stage of energy absorption provided by the inflator bracket 24. In the illustrated example, the deceleration at the second peak 176 is greater than the deceleration at the first peak 174. The second peak 176 is caused by the absorption feature 28 moving from the first absorbing position 32 to the second absorbing position 34. Accordingly, as the center 152 flattens, the rate of declaration increases and then decreases.
The inflator bracket 24 disclosed herein produces lower rates of deceleration compared to the standard bracket. Further, the inflator bracket 24 provides for bi-modal deceleration with the two peaks 174, 176, separated by the vertex 178, to provide two stages of deceleration. The bending and flattening of the absorption feature 28 provide the two stages of energy absorption in response to the predefined force.

Use of the present device may provide for a variety of advantages. For example, the inflator bracket 24 may maintain the space between the air curtain assembly 20 and the vehicle body 14. Additionally, the inflator bracket 24 may operate as an anti-rattle feature to reduce or eliminate the shake-and-rattle of the air curtain assembly 20. Further, the inflator bracket 24 is configured to provide two stages of energy absorption. Moreover, the inflator bracket 24 includes the absorption feature 28 configured to bend from the initial position 30 to the first absorbing position 32 as the distal end 132 moves toward the outer surface 134 to provide the first stage of energy absorption. Additionally, the center 152 is configured to flatten or to deform to a shallower curve 150 during the second stage of absorption as the absorption feature 28 moves to the second absorbing position 34. Also, the center 152 is configured to compress or deform toward the aperture 136 defined by the elongate body 26. Moreover, the inflator bracket 24 provides an efficient package for energy absorption without substantially impinging the space in the passenger cabin 50. Further, the use of the inflator bracket 24 may increase efficiency as additional components, such as a carrier bracket, may be removed from the air curtain assembly 20. Additional benefits or advantages may be realized and/or achieved.
