Description

INFLATABLE GARMENT LINER AND CORRESPONDING GARMENT

TECHNICAL FIELD

[001] The technical field generally relates to an inflatable garment to be worn by a user, and more specifically relates to a selectively inflatable and deflatable liner for the garment.

BACKGROUND

[002] Known inflatable products typically include air cells configured for very specialized applications such as for prostheses intended to improve the comfort of amputees, or air cells included in clothing to improve thermal protection via the insulation provided by the air cells.

[003] Many unknowns and uncertainties still exist in the development and conception of inflatable clothing to meet the requirements of the desired product regarding its insulating capacity, its shock absorption capacity (pressure, elasticity), the fabric used, etc. Therefore, while inflatable clothing has evolved greatly over the years in an attempt to provide optimum protection to the user, there is still a general need for improvements.

DETAILED DESCRIPTION

[0062] As will be explained below in relation to various implementations, the present disclosure describes systems, apparatuses and/or devices to be worn by a user for eliminating, or at least mitigating or reducing the risk of injury related to impacts such as those resulting from falling, for example, while walking or cycling at low speeds.

[0063] In some embodiments, the present disclosure describes a garment, such as a vest or a coat, provided with a liner having an inflatable structure for providing additional protection to the user (e.g., the person wearing the garment). The inflatable structure is selectively operable to inflate and deflate, as desired, in order to provide a corresponding degree or amount of protection to one or more portions of the garment. In some embodiments, operation of the inflatable structure is accomplished using a reversible pump, such as an air pump. The pump can be integrated in the garment, such as stitched into the garment, or simply positioned within a pocket of the garment, for example.

[0064] The liner can include a plurality of inflatable structures provided at various locations to provide protection to corresponding parts of the user’s body. For instance, when the liner is configured to be integrated within a coat, the liner can include arm sections, an upper body section, a lower body section, a neck section, a head section, etc. In some embodiments, each of these liner sections can be provided with an inflatable structure to cover at least a portion thereof. The liner, or at least some of the liner sections, are made of a plurality of layers bonded, or otherwise connected together, where at least one of these layers corresponds to the inflatable structure.

[0065] In some embodiments, the inflatable structure includes at least two layers of high-frequency (HF) weldable material secured together to define an inflatable canvas. Each layer of HF weldable material includes connection regions and inflatable regions, where the connection regions of one layer are superposable and securable with the connection regions of another layer for securing the layers together. The inflatable regions of each layer are similarly superposed together and configured to define a plurality of cells distributed across an area of the HF weldable material layers. The plurality of cells define an array of cells and are configured to inflate and deflate upon operation of the pump in order to adjust the protection provided by the liner (via the inflatable structure). As will be described further below, the cells are in fluid communication with at least one other cell such that each cell of the array of cells can be inflated and deflated as a unit. In other words, inflation and/or deflation of at least one cells can induce inflation and/or deflation of each cell in the array of cells.

[0066] The inflatable structure further includes one or more layers of foam connectable to the inflatable canvas. In some embodiments, the foam can be injected, molded and laminated onto different layers of the inflatable structure, although other configurations are possible. The layer of molded foam is shaped and sized to engage the connection regions of each layer of HF weldable material. It is therefore noted that the molded foam can be adapted to engage the inflatable canvas along regions which are not adapted to inflate (e.g., the connection regions), thereby increasing the protection provided to the garment by the liner and its inflatable structure. It is further noted that providing the molded foam along the non-inflatable regions can assist in limiting the thickness of the foam. In other words, upon inflation of the inflatable canvas, the non-inflatable regions define creases in which the foam can be inserted and connected to the canvas. In some embodiments, the thickness of the foam can be defined and/or selected to generally match the dimensions (e.g., the thickness) of the inflated cells surrounding the foam.

[0067] In some embodiments, the foam layers can include a plurality of foam blocks configured to cooperate with the inflatable canvas and/or with the other foam blocks to increase the protection provided by the liner. More specifically, each foam block can include block sections spaced from one another within a common connection region to enable movement and flexibility of the inflatable canvas. For example, each block section can be positioned adjacent respective cells of the inflatable canvas such that, upon inflation of the inflatable canvas, each cell expands and biases (e.g., pushes) the block sections of a given foam block towards one another (e.g., towards a common center). It should thus be noted that the non-inflated regions of the inflatable canvas, which can correspond to the regions of the inflatable canvas which provides the least protection, are provided with a foam block to cover these regions. The inflatable structure is therefore adapted to provide improved protection across a desired surface area thereof via a combination of the inflatable canvas and the foam blocks, while enabling at least some flexibility from the configuration of the foam blocks (e.g., separate foam sections cooperating with one another). [0068] The liner can include outer layers configured to encapsulate or enclose the inflatable structure to facilitate handling and installing the liner. In some embodiments, the liner is removably connectable to the garment (e.g., to the inner surface of the garment) such that the garment can be worn with or without the liner, as desired. The liner can be connected via any suitable manner or using any suitable mechanism such as one or more zippers, buttons, clips, etc., provided at strategic locations to facilitate incorporating the liner into the garment.

[0069] Furthermore, the garment can include two or more garment sections coupled to one another and configured to move relative to one another. It is noted that inflating the inflatable structure causes the cells to expand, and the overall surface area of the inflatable canvas slightly decreases due to this expansion. More particularly, the inflatable canvas expands in one direction (e.g., along its thickness) and contracts in another direction (e.g., along its length and/or width). The garment sections can at least partially overlap one another such that protection is provided and maintained in the desired portions of the body, even during certain movements and/or upon operation of the inflatable structure. It is appreciated that the relative movement of the garment sections enable and/or facilitate (i.e., does not impede) certain movements performed by the user without reducing the protection provided by the inflatable structure.

[0070] With reference to Figures 1 to 3, a liner 10 for a garment according to an embodiment is illustrated. In this embodiment, the liner 10 is configured to be installed within a coat, such as a winter coat, for example. However, it should be noted that the liner and corresponding parts, as described herein, can be adapted, adjusted and used for different types of garments, such as pants, vests, hoodies, etc. As seen in Figures 1 to 3, the liner 10 includes a plurality of liner sections 11 connectable to one another. For example, the liner sections 11 can include a pair of arm sections 12, an upper body section 14, a lower body section 16 and a neck section 18 connectable to one another using any suitable method, such as, but not limited to stitching, fastening, snapping, or a combination thereof. As will be described further below, the liner 10 can correspond to a protective liner configured to provide additional protection to the garment, and therefore to the user (i.e. , the person wearing the garment).

[0071] Referring to Figure 4, in addition to Figures 1 to 3, the liner 10 (or at least some of the liner sections 11 ) can be formed or made of a plurality of layers bonded, secured and/or otherwise connected together. In this embodiment, the liner 10 includes outer layers 20 adapted to enclose or encapsulate an inflatable structure 22 configured to provide protective properties to the liner 10. In this embodiment, and as seen in Figure 3, each liner section 11 can be provided with an inflatable structure 22 in order to provide protective properties to the corresponding liner section, and therefore to different portions of the liner and associated portions of the garment.

[0072] In some embodiments, each arm section 12 includes respective arm inflatable structures 22a installed proximate a proximal end thereof and adapted to at least partially cover and provide protection to the upper arms and shoulders of the user. The upper body section 14 can be provided with an upper body inflatable structure 22b adapted to cover and provide protection to the back of the user. For example, the upper body inflatable structure 22b can extend from the lower neck and/or the shoulder blades to a midback or lower back region of the user. In some embodiments, the upper body inflatable structure 22b can be further adapted to extend laterally in order to cover and provide protection to at least a portion of the ribcage of the user. The lower body section 16 similarly includes a lower body inflatable structure 22c adapted to cover and provide protection to the lower back, buttocks, hips, coccyx, and a portion of the legs of the user. The neck section 18 include a neck inflatable structure 22d adapted to cover and provide protection to the neck and/or at least a portion of the head of the user.

[0073] It should be understood that the portions of the liner section 11 which do not include the inflatable structure 22 can simply include a single layer of liner material (e.g., a “main lining” 15). In some embodiments, the inflatable structure 22 can be bonded to the main lining 15 and enclosed between the outer layers 20. In other words, in some embodiments, the outer layers 20 are configured to enclose the inflatable structure 22 and therefore do not extend and/or cover the entire surface area of the main lining 15.

[0074] In this embodiment, the liner 10 includes an inflation system 24 selectively operable to actuate the inflatable structure 22. It should be noted that the inflatable structure 22 is actuatable between an inflated configuration for providing protection to the various portions of the liner, and a deflated or idle configuration. The inflation system 24 includes a pump 26 operable to actuate the inflatable structure 22 between the idle configuration and the inflated configuration. In other words, the pump can be operated to inflate (e.g., pump air into) and deflate (e.g., suck air out of) the inflatable structure 22, as desired. In this embodiment, the pump 26 is a reversible air pump, although other configurations are possible. As seen in Figures 1 and 3, the liner 10 can include a pump pocket 27 shaped and adapted to receive and hold the pump 26 therein.

[0075] In this embodiment, the pump 26 is operatively coupled to the inflatable structure 22 of at least one liner section 11 , with the remaining liner sections being coupled to one another to enable actuation thereof upon operation of the pump. It should be noted that other configurations are also possible. For instance, the pump 26 can be the only pump of the inflation system 24 and adapted to be connected to each liner section (e.g., directly). Alternatively, the inflation system can include additional pumps, where each pump is coupled to at least one liner section, for example, where the liner sections are coupled to respective pumps.

[0076] In this embodiment, the pump 26 is operatively coupled to the upper body inflatable structure 22b and to the neck inflatable structure 22d via tubing 28. The upper body inflatable structure 22b can be in fluid communication with the lower body inflatable structure 22c and each of the arm inflatable structures 22a (e.g., via additional tubing 28) to enable inflation thereof. As such, it is appreciated that operation of the pump inflates each one of the inflatable structures of the liner 10. In this embodiment, the inflatable structures 22a, 22b, 22c, 22d are provided with one or more valves 30 to which the tubing 28 can be connected to enable fluid communication between different inflatable structures and/or with the pump 26. In other words, one or more inflatable structures can be directly actuated in the inflated configuration via the pump 26, while other inflatable structures can be indirectly actuated via connections with other inflatable structures.

[0077] Still with reference to Figures 1 to 3, in some embodiments, the inflation system 24 can include one or more sensors 36 configured to monitor one or more parameters of the liner 10 and/or its components, such as the inflatable structure 22. For example, the sensors 36 can include pressure sensors operatively coupled to the inflatable structure 22 for monitoring the internal pressure thereof. After performing various tests, it was determined that the inflatable structure 22 can provide increased protection when operated between about 5 psi and 15 psi, such as at about 8 psi. The pressure sensor can enable monitoring the internal pressure to allow a user to turn off the pump 26 once the pressure sensor indicates the desired pressure (e.g., 8 psi). The pressure sensor can be positioned within the pump pocket 27, which can be provided with a see-through interior surface (e.g., a vinyl surface/window) enabling visuals with the sensor, a corresponding display screen and/or the pump from within the garment. In some embodiments, the sensors 36 can also include temperature sensor(s), external pressure sensor(s) and/or any other suitable sensors or combination thereof.

[0078] In some embodiments, the inflation system includes a control system 38 or controller configured to control operation of the pump in order to maintain the inflatable structure operating at relatively constant parameters. The sensors 36 (e.g., internal pressure sensor, external pressure sensor, temperature sensors, etc.) can be coupled to the controller which collects data recorded by the sensors to operate the pump and adjust the internal pressure of the inflatable structure. It is thus appreciated that the controller can enable automatic or autonomous control, operation and/or adjustment of the inflatable structure of the liner.

[0079] In the present embodiment, the inflation system and inflatable structure are configured to be manually enabled or “turned on”, and remain “on” while the user is wearing the garment. The user can selectively inflate and/or deflate the inflatable structure as desired (e.g., via manual control of the pump), or, as described above, allow a controller to autonomously control the pump. In other words, the inflatable structure is not meant to be operated as an airbag mechanism, which triggers (e.g., inflates) as a reaction to an event, such as an impact or an acceleration (e.g., when falling). However, it should be noted that the system described herein can be alternatively operated as a reactionary system, similar to that of an airbag. For example, accelerometers or impact detection devices can be provided to the liner and coupled to an inflation device configured to rapidly inflate the inflatable structures.

[0080] With reference to Figures 4 to 6, the outer layers 20 of the liner 10 include an outer lining 32 adapted to face the inside of the garment, and an inner lining 34 adapted to be visible when the liner is installed on the garment (e.g., from within the garment). In this embodiment, the outer lining 32 is made of a material configured to define a light and stretchable softshell layer, such as polyester with mechanical stretch or a blend of polyester and spandex, for example. The inner lining 34 can be made of a stretchable material such as nylon and/or spandex, although other materials are possible and may be used. In some embodiments, the outer layers 20 can be coupled or secured to each other at opposite ends of the liner in order to form the internal space and/or enclosure for the inflatable structure. The outer layers 20 can be secured together using an elastic folded binding 35, which can be provided at each end or opening of the liner 10, such as at distal ends of the arm sections 12, around a periphery of the neck section 18 and around a periphery of the lower body section 16 (seen in Figure 1 ). [0081] In this embodiments, the inflatable structure 22 is provided between the outer layers 20 and can be made of a plurality of layers bonded or secured together. For instance, the inflatable structure 22 can include layers of canvas 40 secured together to define an inflatable canvas 42. The inflatable canvas 42 can be provided with the valve enabling connection and fluid communication with the pump and/or with other inflatables canvases 42. The inflatable structure 22 can further include a foam layer 44 connected to an outer surface of the inflatable canvas 42. In some embodiments, the inflatable structure 22 includes a pair of foam layers 44 connected to respective sides of the inflatable canvas 42, either directly or indirectly, as will be described further below. The one or more foam layers 44 are shaped, sized and adapted to cooperate with and reinforce the inflatable canvas 42, thereby increasing the overall protection provided by the inflatable structure 22.

[0082] As seen in Figures 4 and 7 to 10, the inflatable structure 22 can include a pair of canvas layers 40 shaped and sized to be superposed and secured together. In this embodiment, the canvas layers 40 are substantially identical and can be made of high-frequency (HF) weldable material secured together. Each canvas layer 40 can include connection regions 46 and inflatable regions 48. It is thus noted that the connection regions 46 of one canvas layer 40 are superposable with the connection regions 46 of the other canvas layer 40 for securing the layers together. In a similar fashion, the inflatable regions 48 of each canvas layer 40 are superposed together and configured to define a plurality of cells 50 (seen in Figures 5 to 10) distributed across an area of the inflatable canvas 42. The plurality of cells 50 are configured to inflate and deflate upon operation of the pump, which provides increased protection to the garment. In this embodiment, the cells 50 have a typically rectangular or square shape (e.g., with 4 corners). However, it is appreciated that other shapes and/or combinations of shapes are possible and may be used. [0083] With reference to Figures 7 to 10, each cell 50 can be in fluid communication with at least one other cell 50 of the inflatable canvas 42 via links or channels 52 defined between the cells 50. In some embodiments, the pump of the inflation system is operatively coupled to a single cell 50 of the inflatable canvas 42 (e.g., one of the cells 50 is provided with the valve), and each cell is inflated and/or deflated due to their connections with one another via the channels 52. Alternatively, a plurality of cells can be provided with respective valves for enabling multiple cells to be in communication with the pump. In some embodiments, the channels 52 extend between adjacent cells 50 along a side thereof (Figures 7 and 8), although it is appreciated that the channels 52 can extend between cells 50 at their corners (Figures 9 and 10). Other embodiments or combinations thereof are also possible for establishing fluid communication between the cells of the inflatable canvas.

[0084] It is also noted that, upon inflating the inflatable canvas 42, the surface area of the inflatable canvas 42 changes as the inflated cells 50 induce a crumpling of the canvas 42. In other words, inflating the cells 50 of the inflatable canvas 42 reduces the surface area of the inflatable canvas 42. In this embodiment, the foam layer 44 is adapted to dynamically adjust and move together with the changing surface area and configuration of the inflatable canvas 42. The foam layer 44 is configured to cooperate with the inflatable canvas 42 to provide additional protection to the liner, and therefore to the garment, and by extension to the user. The foam layer 44 is configured and positioned so as to not impede movement of the inflatable canvas (e.g., the inflation and deflation of the cells 50) to improve ergonomics (e.g., comfort) and ease-of-use of the inflatable structure. The foam layer 44 can be provided at desired locations along the liner sections 11 or simply across an entire surface area thereof.

[0085] As illustrated, the connection regions 46 are secured together (e.g., welded, HF welded, stitched, etc.) and define non-inflatable regions 45 of the inflatable canvas 42. It is noted that the non-inflatable regions 45 are defined in between each cell 50, adjacent the channels 52 and along a periphery of the canvas 42. The non-inflatable regions 45 provide little to no protection against impacts in those specific areas. Individual non-inflatable regions 45a are defined between the cells 50, whereas a peripheral non-inflatable region 45b is defined along the periphery of the inflatable canvas 42. More particularly, the individual non-inflatable regions 45a are defined between the cells and are further delimited by the channels 52 connecting the cells together. As such, and with reference to Figures 11 to 13, in addition to Figures 7 to 10, the foam layer 40 is connected to the inflatable canvas 42 to at least partially cover the connection regions of the canvas layers, and therefore cover the non-inflatable regions 45 of the inflatable canvas 42. More specifically, in this embodiment, the foam layer 44 is adapted to cover the individual non-inflatable regions 45a defined in a center area of the inflatable canvas 42 in between the cells 50.

[0086] In this embodiment, the layer of foam 44 includes molded foam 54 shaped and adapted to engage the non-inflatable regions 45 of the inflatable canvas 42. More specifically, in this embodiment, the molded foam layer 54 is adapted to cover the individual non-inflatable regions 45a defined in a central area of the inflatable canvas 42 (e.g., in between the cells 50). The molded foam 54 can include foam blocks 56 adapted to engage respective individual non-inflatable regions 45a. The foam blocks 56 can be independent from one another, connected together, or a combination thereof (e.g., some foam blocks being independent, and others being connected).

[0087] With reference to Figures 11 to 13, each foam block 56 can include block sections 58 dispersed within the corresponding region of the inflatable canvas 42. The block sections 58 are shaped and adapted to at least partially conform to the shape of the non-inflatable region 45, the shape of at least one of the cells 50 defining the non-inflatable region 45, or a combination thereof. In some embodiments, the block sections 58 of a given foam block 56 are spaced from each other and are adapted to move relative to one another, for example, upon operation of the pump to inflate or deflate the inflatable canvas 42. In this embodiment, each foam block 56 includes four (4) block sections 58 positioned to engage a corresponding one of the four (4) cells 50 defining the individual non- inflatable region 45a. As illustrated in Figures 7 and 11 , four corners of four different cells 50 cooperate to define a cross-shaped (or "X-shaped") non-inflatable region 45. The block sections of a given foam block engage respective comers defining the cross-shaped non-inflatable region.

[0088] Each block section 58 includes a forward portion 60 having a pair of walls 62 joined at a corner 64. As seen in Figure 11 , the corner 64 is adapted to extend into and engage the non-inflatable region 45. The block section 58 also includes rear portion 66 have a rear surface 68 adapted to at least partially overlap the cell 50 it is engaged with. The rear surface 68 can be flexible and/or have an arcuate shape to conform to the shape of the cell 50, whether it is deflated or inflated. The rear surface 68 is connected to and extends from the walls 62. In this embodiment, the block section 58 is formed as a single piece or monolithic piece of molded foam, although other configurations are possible, such as having separate pieces secured together, for example.

[0089] In this embodiment, when the inflatable canvas is deflated or idle, as seen in Figure 11 , the block sections 58 are spaced from one another. More particularly, the walls 62 and corners 64 are spaced from each other, defining canals 65 therebetween. As the inflatable canvas 42 is initially inflated, as seen in Figure 12, the increased size of each cell 50 biases the block sections towards one another due to the rear surface 68 partially overlapping the cell 50. In other words, the expanding cell pushes against the rear surface 68, which biases the forward portion 60 towards the center of the cross-shaped non-inflatable region 45. It is therefore understood that each block section 58 is biased towards a common center, and therefore towards the other block sections of the foam block. The walls 62 of adjacent block sections 58 are biased to move into the canals 65 and engage one another, while each corner 64 engage each other in the center of the cross- shaped non-inflatable region 45, as seen in Figure 13. It should also be noted that, upon deflating the cells 50 (deflating the inflatable canvas), the block sections 58 revert back to their initial, spaced-apart position, as illustrated in Figure 11 .

[0090] It should thus be understood that the configuration of each foam block 56 enables movement and flexibility of the inflatable canvas, and does not impede movement of the inflatable canvas. It should also be noted that the foam blocks 56 and/or corresponding block sections 58 can have any other suitable shape and configurations. For example, the walls 62 of a given block section 58 can be straight and parallel to the opposing wall of the adjacent cells (as seen in Figure 11 ) such that a surface-to-surface contact is defined as the walls engage one another. Alternatively, the walls can be transverse relative to one another and/or curved such that a punctual contact is defined between the walls upon engaging one another. Similarly, the corners 64 of each block section can move towards a common center such that each corner 64 engages (e.g., contacts) the other comers of the foam block 56. Alternatively, the corners 64 can be misaligned such that the corner of one block section 58 engages a wall 62 of another block section 58, for example.

[0091] As seen in Figures 11 to 13, the rear surface 68 of a block section 58 can cooperate with the rear surface of different block sections 58 of different foam blocks 56. For instance, each block section 58 surrounding a given cell 50 can be part of respective foam blocks 56. These block sections 58 can cooperate with one another to surround the cell 50. It should be noted that the expression "cooperate" can refer to direct contact between the block sections 58 surrounding a common cell 50 or that the block sections 58 are spaced from one another and define a general shape around the cell 50. In this embodiment, the arcuate shape of the rear surfaces 68 of each block section surrounding the cell cooperate to define a circular aperture 70 through which the cell 50 can expand during inflation. [0092] Referring back to Figure 4, the liner 10 includes a plurality of layers, including the inflatable canvas 42 to which the foam layer 44 is bonded. In this embodiment, a layer of adhesive 47 is provided on either side of the inflatable canvas 44 (e.g., one layer of adhesive 47 to each canvas layer 40) to enable connection of the foam layer 44 or any other layer(s). The adhesive layer 47 can include a film of thermoplastic polyurethane (TPU) material, although other configurations are possible. As mentioned, an adhesive layer 47 can be adapted to bond the inflatable canvas 42 with a first foam layer, while another adhesive layer 47 can be adapted to bond the inflatable canvas to the main lining 15. As seen in Figure 4, another adhesive layer 47 is provided to bond a second foam layer 44 to the main lining 15 in order to provide foam layers 44 on opposite sides of the inflatable canvas 42. The outer layers 20 (e.g., the outer and inner linings 32, 34) can then be coupled together about the sections of liner provided with the inflatable structure 22. In some embodiments, a layer of stretch coating 84 can be provided between the foam layer 44 and the inner lining 34 to avoid the foam going through (e.g., showing through) the fabric of the inner lining 34.

[0093] Referring back to Figures 1 , 2 and 5, in this embodiment, the upper and lower body sections 14, 16 are connected to each other in a manner facilitating certain movements of the user. More specifically, a bottom section of the upper body section and a top section of the lower body section at least partially overlap each other to define an overlapping portion 80. Moreover, the liner 10 is configured to enable relative movement between the upper and lower body sections 14, 16. For example, the upper body section 14 can move (e.g., slide) relative to the lower body section 16 along the overlapping portion 80 to facilitate certain movements and maintain a degree of protection provided to the garment by the liner 10.

[0094] In some embodiments, the outer lining 32 of the upper body section 14 can be coupled to the outer lining 32 of the lower body section 16 in an overlapping manner (seen in Figure 5). The overlapping outer linings 32 can define a pleat 82 or fold, where the top end of the lower outer lining is connected to the lower end of the upper outer lining within the pleat 82. This configuration enables relative movement between the upper and lower body sections, and therefore relative movement between respective inflatable structures 22. The amplitude of movement can correspond to the length of the pleat (e.g., the length of the overlap between the outer linings of the two body sections), although other configurations are possible.

[0095] In one example, when the user bends forward, the relative movement between the body sections 14, 16 enables the inflatable structure 22 of the upper body section to slide relative to the inflatable structure 22 of the lower body section 16. Moreover, due to the overlapping portion 80, the inflatable structures 22 do not separate, which would create a gap and an unprotected section of the garment. Instead, the overlapping portion 80 enables the body sections, and respective inflatable structures 22, to move relative to each other, while maintaining the corresponding portion of the garment protected during use (e.g., during certain movements). Similar pleats and overlapping configuration can be implemented in different sections of the liner 10, such as along the arm sections or within the neck section and/or a hood section (not shown).

[0096] In some embodiments, the liner 10 is removably connectable to the garment (e.g., to the inner surface of the garment) such that the garment can be worn with or without the liner. In this embodiment, the liner 10 and garment can each be provided with a corresponding half of a zipper 90. The liner 10 can thus be zipped into the garment when desired. However, it is appreciated that the liner 10 can be connected via any other suitable manner or using any suitable mechanism such as using additional zippers, buttons, clips, etc., provided at strategic locations to facilitate incorporating the liner into the garment. In this embodiment, the main lining layer 15 and outer lining 32 are joined together along the zipper 90 which can facilitate connection of the liner with the garment. However, it is appreciated that other configurations are possible, such as providing the zipper to a layer of the inflatable structure, for example. It should be noted that removably connecting the liner 10 to the garment enables removal thereof, for example, when putting the garment in a washing machine. This protects the pump, the sensors and any other parts or components which could be damaged from being submerged. It should be noted, however, that the liner 10 can alternatively be permanently stitched into the garment.

[0097] As described herein, the inflation system 24, or at least a portion thereof, such as the pump 26, are integral to the liner 10. Alternatively, the pump 26 can be disconnectable and removable, thus enabling the inflation system to be removed from the liner 10. It is appreciated that the inflation system 24 includes electronics and devices which do not pair well with humidity and water. Therefore, enabling removal thereof can enable cleaning the liner 10, for example, in a washing machine. It is further noted that, by enabling removal of the inflation system 24, the inflatable garment can be separated into three (3) subassemblies, including the garment, the liner and the inflation system. These three subassemblies can be selectively connected and disconnected, as desired.

[0098] It should be appreciated from the present disclosure that the various embodiments of the liner and related components provide consistent and improved protection to a garment, and therefore to the person wearing the garment. The cooperation between the inflatable canvas and the molded foam increases the protection provided in certain areas, and the overlapping connection between adjacent liner sections increases comfort of the user, for example, while accomplishing certain tasks or doing certain movements. Furthermore, the inflatable canvas is selectively operable via input from the user to inflate and deflate. Sensors and control systems can be implemented to enable autonomous adjustments of the inflatable structure in order to provide a constant degree of protection, no matter the external conditions.

[0099] It should also be appreciated that the combination of the inflatable canvas, which can be selectively inflated, and the one or more layers of foam provide increased protection to the user against impacts sustained, for instance, from falls or slips occurring during active mobility, such as while walking or running. The combination of air pockets (e.g., the inflatable cells of the canvas) and molded foam can be configured to reduce the impact forces (or a load transfer of the impact forces) and/or absorb the impact forces (or the load transfer of the impact forces) resulting from such falls, thereby increasing protection of the user.

[00100] The present disclosure may be embodied in other specific forms without departing from the subject matter of the claims. The described example embodiments are to be considered in all respects as being only illustrative and not restrictive. The present disclosure intends to cover and embrace all suitable changes in technology. For example, in some embodiments, the inflation system can include an air release mechanism in addition to, or as an alternative to operating the pump to deflate the inflatable structure. The air release mechanism can include an air release valve or air release button actuatable to release/evacuate the air from the inflatable cells. In other embodiments, the valves of the inflation system can be on/off valves selectively operable to allow and/or prevent fluid flow therethrough. As such, inflatable structures of certain liner portions can be “turned off” by closing the valve which enabled inflation of the cells of those inflatable structures, for example.

[00101] In some embodiments, the inflation system can be provided with visual indicators, such as LEDs, configured to provide visual indication to the user of various events and/or conditions. For example, prior to inflating the inflatable structure, an LED indicator can shine/flash/emit a red light, signaling that the inflatable structure is idle. During inflation and/or deflation, the LED can emit a yellow light, and once fully inflated, the LED can emit a green light, signaling that the inflatable structure is inflated. The green light (or another color) can also indicate that the inflatable structure is inflated and within a predetermined range of pressures, for example. A display screen can also be provided to enable the user to take notice of the readings from the sensors. [00102] In addition, some portions of the liner can be further provided with a layer of viscoelastic foam. For instance, portions of the liner which are not provided with the inflatable structure, such as the distal half of the arm sections, or the lateral sections of the upper body section can be provided with respective layers of viscoelastic foam in order to provide at least some protection to these areas. In some embodiments, the inflation system can include sensory notification devices, such as various LEDs to indicate the level of the battery of the electric pump (e.g., green, yellow and red LEDs). The sensory devices can include a mechanism configured to vibrate or emit a sound if a leak is detected in the tubing of the inflation system.

[00103] In other embodiments, the layers of foam of one or more inflatable structures (of one or more liner sections) can include one or more sheets of foam cut to size (e.g., die cut) and assembled, such as via stitching, to the other layers of the inflatable structure. The sheets of foam can be independent from the rest of the layers of the inflatable structure and configured to be “wedged” between at least two other layers, such as the inflatable canvas and the outer lining, for example.

[00104]As used herein, the terms “coupled”, “coupling”, “attached”, ’’connected” or variants thereof can have several different meanings depending in the context in which these terms are used. For example, the terms coupled, coupling, connected or attached can have a mechanical connotation. For example, as used herein, the terms coupled, coupling or attached can indicate that two elements or devices are directly connected to one another or connected to one another through one or more intermediate elements or devices via a mechanical element depending on the particular context.

[00105] In the present disclosure, an embodiment is an example or implementation of the described features. The various appearances of “one embodiment,” “an embodiment” or “some embodiments” do not necessarily all refer to the same embodiments. Although various features may be described in the context of a single embodiment, the features may also be provided separately or in any suitable combination. Conversely, although the garment, liner and/or associated components may be described herein in the context of separate embodiments for clarity, it may also be embodied in a single embodiment. Reference in the specification to “some embodiments”, “an embodiment”, “one embodiment”, or “other embodiments”, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily in all embodiments.

[00106] In the above description, the same numerical references refer to similar elements. Furthermore, for the sake of simplicity and clarity, namely so as to not unduly burden the figures with several references numbers, not all figures contain references to all the components and features, and references to some components and features may be found in only one figure, and components and features of the present disclosure which are illustrated in other figures can be easily inferred therefrom. The embodiments, geometrical configurations, materials mentioned and/or dimensions shown in the figures are optional, and are given for exemplification purposes only.

[00107] In addition, although the optional configurations as illustrated in the accompanying figures comprises various components and although the optional configurations of the liner as shown may consist of certain geometrical configurations as explained and illustrated herein, not all of these components and geometries are essential and thus should not be taken in their restrictive sense, i.e. , should not be taken as to limit the scope of the present disclosure. It is to be understood that other suitable components and cooperations thereinbetween, as well as other suitable geometrical configurations may be used for the embodiment and use of the liner, and corresponding parts, as briefly explained and as can be easily inferred herefrom, without departing from the scope of the disclosure.
