Description

[Technical Field]

[0001] The present invention relates to a wearable protective device having an inflatable member. Furthermore, the present invention relates to a method for safely activating the inflatable member of said wearable protective device.

[0002] In particular, the present invention relates to a wearable protective device comprising an inflatable member suitable for use in any field where effective protection against impacts and / or falls needs to be obtained, for example the wearable protective device is suitable for being worn by motorcyclists, cyclists, skiers or during work activities. [Background technology]

[0003] For clarity, reference will be made herein to, but is not limited to, wearable protective equipment suitable for being worn by motorcyclists.

[0004] Typically, the wearable protective device comprises a protective garment, such as a jacket, suit, vest, or belt, which includes an inflatable member adapted to transition from a rest state in which it is deflated to an operational state in which it is inflated.

[0005] The inflatable member is in fluid communication with an inflator device, such as a gas cartridge, adapted to introduce a predetermined amount of inflation fluid, such as compressed gas, into the inflatable member, causing it to inflate and thus expand.

[0006] The release of inflation fluid may be controlled by a mechanical or electronic system.

[0007] The gas cartridge typically consists of a cylindrical housing having a first end connected to the opening of the inflatable member and, in the case of electronically activated systems, a second end connected by a specific connector to the control unit of the wearable device.

[0008] Connection of the gas cartridge to the inflatable member can be performed by clamping the end of the cartridge directly into the opening of the inflatable member, or the end of the gas cartridge can be provided with external threads suitable for being screwed inside corresponding threads of a cap placed over the opening of the inflatable member.

[0009] Alternatively, the end of the gas cartridge may be connected to the inflatable member by a bayonet mount, in which case the male element is provided on the end of the gas cartridge and the female receptor is provided on a cap positioned over the opening of the inflatable member.

[0010] In known devices, after being inflated, the inflatable member can be reused if it is not damaged, such as torn or punctured.

[0011] Conversely, unless the gas cartridge is provided with more than one inflation charge, it will need to be replaced with a new gas cartridge after each deployment.

[0012] However, replacing gas cartridges is a potentially dangerous operation if not managed properly.

[0013] In practice, in order to achieve high performance in terms of pressure and deployment time without increasing the size of the gas cartridge, the gas cartridge usually contains a pyrotechnic charge.

[0014] In the case of an electronically activated airbag system, the pyrotechnic charge is ignited by an electronic impulse coming from a control unit, and in the case of a mechanically activated airbag, the pyrotechnic charge is backed by a mechanical firing pin.

[0015] Even if a manufacturer follows standard safety procedures to ensure the safe operation of a gas cartridge, there is a possibility that the electronic or mechanical controls on the cartridge may fail or that a user may not handle the cartridge properly during operation and / or replacement.

[0016] To avoid any safety hazards to the end user, gas cartridge replacement is currently handled by certified centers that are specially trained to handle pyrotechnic components and to ensure the correct connection of the gas cartridge and the inflatable member.

[0017] In the case of an electronically activated system, to replace a depleted gas cartridge, the electronic connector to the control unit must first be released from the gas cartridge, and then the end of the gas cartridge connected to the inflatable member must be removed from the inflatable member.

[0018] However, either operation can result in the accidental triggering of the pyrotechnic charge in the gas cartridge, with great risk to the operator.

[0019] At the same time, even if the gas cartridge is replaced in a safe manner, the protection of the user could be compromised.

[0020] In fact, if the new gas cartridge is not properly secured to the inflatable member, proper inflation of the inflatable member may be prevented, with great risk to the end user.

[0021] In particular, the triggering of a gas cartridge that is not coupled or improperly coupled to the inflatable member may not only render the inflatable protective device ineffective, but it may also be dangerous to the user, as the gas cartridge or connecting cap may be fired towards the user's body.

[0022] Another risk to the user is that if the gas cartridge is not or is not properly connected to the inflatable member, either directly or via a connection cap, the outward flow of inflation gas can result in injury to the user, such as cuts or burns.

[0023] In view of the above problems, if the inflatable member is activated during use of the wearable protective device, the wearable protective device needs to be returned to an authorized center to perform a gas cartridge replacement.

[0024] However, transporting wearable protective equipment is costly due to the bulkiness of the garments.

[0025] Furthermore, unless the user has another inflatable protective garment at their disposal, with associated and non-negligible costs, the user will be deprived of the additional protection provided by the inflatable wearable protective device for at least a period of time, typically two to three weeks.

[0026] A solution to the above technical problem is disclosed in patent application WO 02 / 049999, filed in the name of the same applicant.

[0027] In particular, the patent application WO 2007 / 024444 discloses a wearable protective device with a safety device that is designed to signal an unsafe state of the wearable protective device if the inflator device becomes detached or is not properly coupled to the inflatable member.

[0028] In the embodiment disclosed in the '691 patent, the inflator device is designed to be inserted into a retaining sheet, which may be provided with a suitable cover to protect the inflator device.

[0029] The cover may be provided with first fastening means designed to mate with corresponding second fastening means of the carrier sheet, allowing fastening of the cover to the carrier sheet.

[0030] The first and second fastening means are designed to be coupled to one another only when the safety device allows the insertion of the inflator device into the retaining seat.

[0031] In fact, if the inflator device in the form of a gas cartridge cannot be inserted into the retaining seat, the cover cannot be properly fixed to the retaining seat, since the inflator device will protrude from the retaining seat.

[0032] The above solution is highly appreciated as it provides the user with clear and reliable feedback regarding the connection between the inflator device and the inflatable member, and allows end users without special training to understand whether the inflator device is properly connected to the inflatable member.

[0033] However, the above-mentioned solution does not prevent the cover from being fixed to the retaining sheet in the complete absence of an inflator device or of the assembly formed by the inflator device and the cap fixed to the inflatable member, i.e. in the case where, for some unforeseen reason, the cover is fixed to the retaining sheet without previously inserting an inflator device into that sheet.

[0034] In this case, visual inspection of the wearable protective device may lead to the erroneous conclusion that the inflatable member may be inflated in case of danger, when in fact the inflatable member lacks one of the components essential for its proper inflation.

[0043] 1 and 2, an example of a wearable protective device according to the present invention is designated generally by the reference numeral 10. As shown in FIG.

[0044] The wearable protective device 10 may be, for example, a garment such as a jacket or suit, or alternatively, may be an undergarment suitable for use in combination with outer protective clothing.

[0045] In a further embodiment, the wearable protective device 10 may be a harness designed to be worn over or under another garment.

[0046] Advantageously, the wearable protective device may be a device for protecting the body of a user, particularly the elderly, from injuries resulting from impacts and falls, in which case the wearable protective device may be shorts or briefs designed to protect the waist of the user.

[0047] Alternatively, the wearable protective device may be a protective element such as, for example, a helmet.

[0048] Wearable protective device 10 is preferably designed to be worn by motorcyclists, however, as will become more apparent from the following description, wearable protective device 10 may also be advantageously used by cyclists, skiers, workers, or in other fields where effective protection of the user's body needs to be obtained.

[0049] The wearable protective device 10 includes at least one inflatable member 12. The inflatable member 12 is designed to move between a deflated rest state and an inflated activated state. The inflatable member 12 can be inflated with a fluid, such as air or gas, to expand to protect the user of the wearable protective device 10 from impacts, falls, or slips.

[0050] In the embodiment shown in FIGS. 1 and 2, the wearable protective device 10 is provided with a single inflatable member 12 .

[0051] Advantageously, such inflatable member 12 is designed to be placed on the chest and / or back and / or shoulders and / or sides of the user. Obviously, different placements of inflatable member 12 are possible to meet other specific needs.

[0052] The wearable protective device 10 may be provided with a single inflatable member 12 or with multiple inflatable members adapted to cover different parts of the user's body.

[0053] Preferably, the expandable member 12 has a bladder-like shape.

[0054] As shown schematically in Figures 3 and 4, wearable protective device 10 also includes at least one inflator device 14 coupled to inflatable member 12 and designed to inflate inflatable member 12 when inflator device 14 is triggered.

[0055] Preferably, the inflator device 14 is selected from the group including a pyrotechnic inflator, a compressed gas inflator, and a hybrid inflator.

[0056] Inflator device 14 may include multiple inflation charges, in which case inflatable member 12 may be inflated more than once, allowing for inflation at different periods of time.

[0057] In such a situation, once all inflation charges have been triggered, a replacement of the inflator device 14 must be performed.

[0058] As shown in the accompanying drawings, the inflator device 14 is preferably in the form of a cylindrical gas cartridge.

[0059] 3, the inflator device 14 has a connecting end 16 designed to be connected to the inflatable member 12. Specifically, the connecting end 16 is preferably airtightly inserted into an opening 18 of the inflatable member 12 and closed.

[0060] As is known in the art, the connecting end 16 of the inflator device 14 may be removably connected to the inflatable member 12 by connecting means designed to ensure an airtight connection. Within the meaning of the present invention, the connecting means is considered to be part of the inflator device.

[0061] 3 and 11, such connection means may include a connection cap 20 designed to be secured to the opening 18 of the expandable member 12. Preferably, the cap is secured within the opening 18 by a clamp 22 (see FIG. 3).

[0062] Alternatively, the connecting end 16 of the inflator device 14 may be fitted and secured to the connecting cap 20 .

[0063] Preferably, the connection end 16 of the inflator device 14 may be provided with external threads suitable for being threaded into corresponding internal threads provided on the inside of the connection cap 20 (see FIG. 3).

[0064] The inflator device 14 may be triggered by an electrical or mechanical mechanism. In the case of electrical activation, the wearable protective device 10 includes at least one sensor 24 designed to detect a force acting on the wearable protective device 10.

[0065] The sensor 24 may be applied, for example, to the shoulder portion of the wearable protection device 10 (see FIG. 1).

[0066] The sensor 24 may be an accelerometer designed to detect acceleration acting on the wearable protective device 10 or a gyroscope designed to detect the movement and orientation of the wearable protective device 10 .

[0067] Preferably, the wearable protective device 10 includes a plurality of sensors 24 .

[0068] The wearable protective device 10 may further include a control unit 26 (see FIG. 1) designed to process the data detected by the sensor 24 and to send a trigger signal to the inflator device 14 when a crash situation is identified.

[0069] By "crash situation" is meant a situation in which the wearable protection device 10 experiences a sudden acceleration / deceleration and / or a sudden change in its orientation and its angular velocity.

[0070] In particular, if the user of the wearable protective device 10 is riding a vehicle such as a motorcycle, a sudden acceleration or deceleration experienced by the wearable protective device 10 may identify that the motorcycle has collided with an obstacle or that the user has been thrown from the saddle and lost control of the motorcycle.

[0071] The control unit 26 is designed to process the data received from the sensors 24 at regular time intervals (for example 1 millisecond) in order to obtain information about the forces acting on the wearable protective device 10 .

[0072] When the control unit 26 detects, based on an algorithm implemented therein, that a crash situation is occurring, a trigger signal may be sent from the control unit 26 to the inflator device 14, causing the inflatable member 12 to inflate.

[0073] In the case of mechanical activation of the inflator device 14, the inflator device 14 may be triggered using an activation cable or tether connecting the wearable protective device 10 to a vehicle, such as a motorcycle, or, if the wearable protective device is used by a worker, a ladder.

[0074] The activation cable has a first end connected to the motorcycle or ladder and a second end secured to a trigger device designed to trigger a firing pin which, in turn, is configured to activate the inflator device 14.

[0075] In the event of a user separation from the motorcycle or ladder, typically caused by a fall and / or impact, the activation cable or tether triggers the firing pin via the trigger device, resulting in deployment of the inflator device.

[0076] The activation cable can also be activated manually.

[0077] In the case of electrical activation of the inflator member 12, the inflator device 14 is electrically connected to a control unit 26.

[0078] In particular, the inflator device 14 is connected to a control unit 26 by a cable having an electronic connector 28 at its end (see, eg, FIGS. 4 and 6).

[0079] Alternatively, the inflator device 14 may be wirelessly connected to the control unit 26 .

[0080] As shown in FIGS. 1 and 2, the wearable protective device 10 also includes a housing designed to house the inflator device 14 .

[0081] Advantageously, the housing may also house the control unit 26 and sensor 24 of the wearable protective device 10 in addition to the inflator device 14 .

[0082] The housing 30 is preferably box-shaped.

[0083] Advantageously, the housing 30 may comprise a base 32 and a cover portion 34 designed to be secured together (see, for example, FIG. 6).

[0084] Preferably, the base 32 and cover portion 34 are secured together by removable fastening means such as rivets, bolts, or snap connectors.

[0085] Advantageously, the base 32 defines a storage cavity 36. Preferably, said storage cavity 36 is defined by a peripheral wall 37 of the base 32.

[0086] The storage cavity 36 may be selectively closed by a cover portion 34, which acts as a lid for the storage cavity.

[0087] In the closed configuration, the housing 30 is provided with an opening that allows the passage of any cables that connect the inflator device 14 to the control unit 26 or another element, and an opening that is in close proximity to the inflator device 14 and allows the accommodation of a portion of the inflatable member 12.

[0088] 1, the housing 30 can be applied directly to the wearable protective device 10. For example, if the wearable protective device 10 is a garment, the housing 30 can be inserted into a pocket 11 provided in the garment, or it can be secured to the inner or outer surface of the garment.

[0089] Preferably, the housing 30 is located on the back of the garment.

[0090] Alternatively, the housing 30 may be applied indirectly to the wearable protective device 10. For example, as shown in FIG. 2, the housing 30 may be applied to the wearable protective device by means of an additional protective element 13 secured to the wearable protective device 10.

[0091] 2, the wearable protection device 10 may be a vest equipped with a back protector 13. In this case, the housing 30 may be inserted into a seat provided in the back protector 13 and fixed to the back protector 13.

[0092] According to the present invention, the housing 30 comprises a detection means 33 adapted to move between a first configuration and a second configuration. In particular, insertion of the inflator device 14 into the retaining seat 40 of the housing 30 causes the detection means 33 to move from the first configuration to the second configuration.

[0093] As will become apparent from the following description, the detection means 33 is capable of detecting the presence of the inflator device 14 within the housing 30 and providing reliable feedback to the user as to such condition.

[0094] In particular, movement of the detection means 33 from its first configuration to its second configuration will result in a mechanical or electrical output that signals that the inflator device 14 is properly inserted within the housing 30 and is thereby ready to inflate the inflatable member 12.

[0095] 4-19, the detection means 33 may comprise spacing means 38. Advantageously, in a first configuration, the spacing means 38 is adapted to keep the base 32 and cover portion 34 of the housing 30 spaced apart, and in a second configuration, the spacing means 38 is suitable to allow the cover portion 34 to rest against the base 32.

[0096] In particular, insertion of the inflator device 14 into its retaining seat 40 causes the spacing means 38 to move from the first configuration to the second configuration.

[0097] By providing the spacing means 38, the cover portion 34 can be secured to the base 32 of the housing 30 only when the inflator device 14 is properly inserted into its retaining seat 40.

[0098] If the inflator device 14 is not properly inserted into the retaining sheet 40, or if the user forgets to insert the inflator device 14 into the housing 30, the spacing means 38 will therefore remain in its first configuration, thereby keeping the base 32 and cover portion 34 spaced apart and not allowing those elements to be secured to one another.

[0099] In this way, the user has easy and reliable feedback as to the fact that the wearable protection device 10 is not in an appropriate state to allow inflation of the inflatable member 12.

[0100] Similarly, spacing means 38 may be designed to remain in its first configuration even when inflator device 14 is not coupled or properly coupled to inflatable member 12 .

[0101] Indeed, as will be explained in more detail below, the spacing means may also be designed to detect the presence of any connecting cap used to connect the inflator device to the inflatable member.

[0102] At the same time, when the inflator device 14 is inserted in the retaining sheet 40 in the proper manner and properly coupled to the inflatable member 12, the spacing means 38 is adapted to move to its second configuration, thereby allowing the cover portion 34 to abut against the peripheral wall 37 of the base 32. In this way, the cover portion 34 is allowed to be secured to the base 32, and thus the user has assurance that the inflator device 14 is properly inserted into its retaining sheet 40 and that the inflatable member 12 of the wearable protective device 10 can be safely activated if required.

[0103] In other words, the spacing means 38 can detect the presence of the inflator device 14 and allow proper closure of the housing 30 only when the inflator device 14 is correctly inserted into its retaining seat 40 and properly coupled to the inflatable member 12.

[0104] As shown in the accompanying figures, spacing means 38 may be disposed between the base 32 and cover portion 34 of the housing 30 .

[0105] Preferably, spacing means 38 is secured to base 32 and disposed within a receiving cavity 36 defined by base 32 .

[0106] Alternatively, the spacing means 38 may be fixed to the cover portion 34 .

[0107] Preferably, the spacing means 38 is hinged to a support member 42 of the base 32 (see FIG. 12 or FIG. 16). The support member 42 may be provided on the bottom wall of the base 32.

[0108] Advantageously, according to the first embodiment, the spacing means 38 can rotate about a pivot point 44 of the support member 42. Preferably, said pivot point 44 extends along the longitudinal axis L of the housing 30 (see Figure 12). As shown in the accompanying figures, the longitudinal axis L of the housing 30 extends substantially parallel to the longitudinal axis W of the inflator device 14.

[0109] In another embodiment not shown in the accompanying figures, the spacing means may rotate about a pivot point extending along an axis disposed along a different direction.

[0110] For example, as shown in FIG. 12, the pivot point 44 may consist of a pin inserted between two shoulders 45 of the support member 42, the pin 44 engaging an articulation hole 46 provided in the bottom of the spacing means 38.

[0111] Preferably, a resilient means 48 is disposed between the support member 42 and the spacing means 38, and rotation of the spacing means 38 from the first configuration to the second configuration occurs by overcoming the resilient force exerted by the resilient means 48.

[0112] In particular, the resilient means 48 may comprise a coil spring having a first end 49 abutting the base 32 or support member 42 and a second end 50 abutting the spacing means 38. Preferably, said second end 50 is inserted into a seat 53 located at the bottom of the spacing means 38.

[0113] In particular, the resilient means 48 may press against the spacing means 38 at a second end 50 and interact with the base 32 or support member 42 at an opposite first end 49 .

[0114] The provision of the resilient means 48 prevents inadvertent movement of the spacing means 38 from the first configuration to the second configuration. Similarly, the resilient means 48 ensures that the spacing means 38 returns to its first configuration when the inflator device 14 is removed from its retaining sheet 40.

[0115] For example, as shown in Figures 7-13, spacing means 38 may include at least one lever 39. Preferably, lever 39 is L-shaped having a first arm 52 engageable with base 32 of housing 30 and a second arm 54 engageable with inflator device 14.

[0116] In particular, the first arm 52 of the L-shaped lever 39 lies in a plane substantially parallel to the bottom surface of the base 32, while the second arm 54 of the L-shaped lever 39 extends along a direction substantially perpendicular to the bottom surface of the base 32.

[0117] In the first configuration, the first arm 52 of the lever 39 abuts against a counterpart 56 provided on the bottom surface of the base 32 .

[0118] Advantageously, said counterpart 56 can be arranged at the base of the support member 42 (see FIG. 12).

[0119] When the lever 39 is fixed to the support member 42, the counterpart 56 is preferably arranged offset with respect to the articular hole 46 of the lever 39. Advantageously, the counterpart 56 is interposed between the retaining seat 40 and the articular hole 46.

[0120] In this way, the counterpart 56 can function as a wedge that allows rotation of the lever 39 in only one direction when force is applied to the second arm 54, with rotation in the opposite direction being prevented by abutment between the counterpart 56 and the first arm 52.

[0121] Advantageously, due to the mutual positioning between the corresponding portion 56, the articulation hole 46 and the retaining seat 40, when the lever 39 is in its first configuration, the lever 39 can only rotate in a direction away from the retaining seat 40 into which the inflator device 14 is inserted.

[0122] The rotation of the lever 39 between the first and second configurations is shown diagrammatically in FIG. 8, with the direction of rotation experienced by the lever 39 indicated by arrow A.

[0123] In particular, in the first configuration, the distal end 58 of the second arm 54 is designed to protrude from the base 32, and in particular from the storage cavity 36 defined therein, preventing the cover portion 34 from resting against the base 32 and closing the storage cavity 36 (see, e.g., FIG. 9).

[0124] In the second configuration, after rotation of the lever 39 about the pivot point 44, the distal end 58 of the second arm 54 is designed to retract into the base 32, and in particular into the storage cavity 36 defined therein, allowing abutment between the cover portion 34 and the base 32. After such abutment, the cover portion 34 may thus be secured to the base 32 and close the storage cavity 36.

[0125] Alternatively, according to the embodiment shown in Figures 14-19, spacing means 38 may be coupled to support member 42 of base 32 and adapted to move along lateral axis T of housing 30. In Figures 16-17, the direction of movement experienced by spacing means 38 is indicated by the letter B.

[0126] In this embodiment, spacing means 38 preferably comprises at least one stem 70 and at least one rod 74 coupled together, said at least one rod 74 being slidably inserted between shoulders 45 of support member 42. Stem 70 and rod 74 may be made integrally.

[0127] Alternatively, the stem 70 may be rigidly coupled to the rod 74 .

[0128] 16 and 17, stem 70 is preferably positioned perpendicular to rod 74. The assembly formed by stem 70 and rod 74 is T-shaped, with rod 74 designed to slidably engage a corresponding hole in shoulder 45 of support member 42.

[0129] The geometry of the connection between the rod and the hole in shoulder 45 is designed to prevent any rotation of the rod about axis T.

[0130] Similar to the previously disclosed embodiment, the resilient means 48 is disposed between the support member 42 and the spacing means 38, and movement of the spacing means 38 from the first configuration to the second configuration occurs by overcoming the resilient force exerted by the resilient means 48.

[0131] In particular, the elastic means 48 may comprise a coil spring having a first end abutting the support member 42, i.e. the shoulder 45 of the support member 42, and a second end abutting the stem 70.

[0132] In particular, the resilient means 48 may press, at its second end, against the spacing means 38 , i.e. the stem 70 , and, at its opposite first end 49 , against the support member 42 , i.e. the shoulder 45 of the support member 42 .

[0133] Again, the provision of resilient means 48 prevents inadvertent movement of spacing means 38 from the first configuration to the second configuration.

[0134] For example, as shown in Figures 15-19, the rod 74 is engageable with the inflator device 14, and the stem 70 is engageable with an abutment portion 72 provided on the inner surface 35 of the cover portion 34. The inner surface 35 is the surface of the cover portion 34 that faces the base 32.

[0135] In particular, the rod 74 lies in a plane substantially parallel to the bottom surface of the base 32 , while the stem 70 extends along a direction substantially perpendicular to the bottom surface of the base 32 .

[0136] In the first configuration (see FIG. 18), when the cover portion 34 is positioned near the base 32, the stem 70, specifically the distal end 73 of the stem 70, is designed to abut against the abutment portion 72.

[0137] In particular, the heights of stem 70 and abutment 72 are selected to prevent cover portion 34 from closing base 32, and in particular from closing storage cavity 36. The contact between stem 70 and abutment 72 keeps base 32 and cover portion 34 spaced apart so as not to allow these elements to be secured together.

[0138] In moving to the second configuration (see FIG. 19), the rod 74 moves along the lateral axis T, which causes a corresponding movement of the stem 70, which will no longer be positioned relative to the abutment portion 72 when the cover portion 34 is positioned near the base 32.

[0139] In this manner, the cover portion 34 can be positioned in contact with the base 32, thereby allowing the cover portion 34 to be secured to the base 32 and closing the storage cavity 36, with the stems 70 and abutment portions 72 arranged in an alternating configuration within the storage cavity 36.

[0140] Alternatively, as shown in Figures 20-24, the detection means 33 may include one or more detectors 80, 90, 100 designed to detect the presence of the inflator device 14 within its retaining seat 40. The detectors 80, 90, 100 are preferably located on the base 32 adjacent to the retaining seat 40.

[0141] However, the detector can also be arranged in an area of ​​a cover part designed to overlap or to partially form the retaining sheet 40 .

[0142] As with the previously disclosed embodiments, detectors 80, 90, 100 are designed to move from a first configuration to a second configuration when inflator device 14 is present within housing 30, and particularly when inflator device 14 is inserted into its retaining seat 40.

[0143] Advantageously, the detectors 80, 90, 100 are adapted to electrically signal another element of the wearable protection device 10 when they move from the first configuration to the second configuration.

[0144] The movement of detectors 80, 90, 100 from the first configuration to the second configuration may be signaled electrically, for example by connector 84, to control unit 26 of wearable protective device 10, or alternatively may be signaled to an additional signaling device (e.g., a visual or audible signaling device not shown in the accompanying figures) that may notify the user that inflator device 14 has been properly inserted into housing 30.

[0145] Unlike the spacing means 38 of the embodiment of FIGS. 3-19 , the detectors 80, 90, 100 cannot prevent the cover portion 34 from being secured to the base 32 if the inflator device 14 is not inserted into its retaining seat 40. However, the detectors 80, 90, 100 are adapted to provide clear and reliable feedback to the user about the presence of the inflator device 14 within the housing 30. In any case, if the inflator device 14 is electrically activated by the control unit 26, the control unit 26 can be programmed to switch the detectors 80, 90, 100 to an "on state" if the detectors 80, 90, 100 are in the second configuration and thus the inflator device 14 is inserted into its retaining seat 40. In the "on state," the control unit can send a trigger signal to the inflator device 14 in the event of a dangerous situation. If not in the "on state," the control unit cannot send a trigger signal to the inflator device 14.

[0146] Referring to FIGS. 20-24, the detector can be a mechanical switch 80, a proximity sensor 90, or a photocell sensor 100.

[0147] However, different types of sensors may be used to meet particular needs.

[0148] The mechanical switch 80 may be a limit switch (see FIGS. 20-22). Preferably, the limit switch 80 is provided with an actuation arm 82 designed to move from a first configuration in which it is in an inactivated state to a second configuration in which it is activated. In particular, as shown schematically in FIG. 22, the arm 82 is actuated by the presence of the inflator device 14 within the retaining seat 40. In particular, the arm 82 is designed to bend when it contacts the outer surface of the inflator device 14.

[0149] 23, the detector may be a proximity sensor 90. The proximity sensor 90 can detect the presence of the inflator device 14 within the retaining sheet 40 without physically contacting the inflator device 14.

[0150] The proximity sensor 90 is provided with a sensing surface 92 designed to detect the presence or absence of the inflator device 14 within its retaining seat 40 .

[0151] In particular, the proximity sensor is in a first configuration when the sensing surface 92 detects the absence of the inflator device 14, and the proximity sensor is in a second configuration when the sensing surface 92 detects the presence of the inflator device. The presence of the inflator device is detected when the distance between the inflator device and the sensing surface is within the sensing range of the sensing surface.

[0152] The proximity sensor 90 can be optical, laser, or ultrasonic.

[0153] 24, the detectors may be two photocell sensors 100. Preferably, the photocell sensors 100 are located on opposite sides of the retaining sheet 40 of the inflator device 14.

[0154] One photocell sensor 100 is provided with a light-emitting surface 102 and one photocell sensor 100 is provided with a light-receiving surface 104 .

[0155] Additionally, the photocell sensor 100 can detect the presence of the inflator device 14 within the retainer sheet 40 without physically contacting the inflator device 14 .

[0156] In particular, the photocell sensor 100 is in a first configuration when the light-emitting surface 102 and the light-receiving surface 104 detect the absence of an inflator device 14, and in a second configuration when the light-emitting surface 102 and the light-receiving surface 104 detect the presence of an inflator device. The presence of an inflator device is detected when the inflator device 14 is located between the light-emitting surface 102 and the light-receiving surface 104, i.e., between the sensor 100. Indeed, in this case, the light emitted from the light-emitting surface 102 is blocked by the inflator device 14 and does not reach the light-receiving surface 104.

[0157] As previously anticipated, the detection means 33 is designed to move to its second configuration only when the inflator device 14 is properly contained within its retaining seat 40 disposed within the housing 30.

[0158] In the preferred embodiment, the retaining seat 40 of the inflator device 14 is mounted on the base 32 of the housing 30 .

[0159] Preferably, the retention sheet 40 is defined by one or more abutment surfaces 60 that define a sheet that is complementary to the shape of the inflator device 14 .

[0160] The retaining sheet 40 may also be defined by one or more recesses in the base or cover portion.

[0161] Advantageously, the abutment surface 60 may protrude from the base 32 of the housing 30 and is designed to securely secure the inflator device 14 when it is inserted within the housing.

[0162] Advantageously, the retaining sheet 40 is also designed to accommodate the connecting means by which the inflator device is connected to the inflatable member.

[0163] In particular, the retaining sheet 40 may be designed to accommodate the inflator device 14 and the connection cap 20 (see FIGS. 11 and 15). In particular, the abutment surface 60 may be disposed along the base 32 of the housing 30 and define a profile complementary to the assembly formed by the inflator device 14 and the connection cap 20. In this manner, the inflator device 14, when secured to the inflatable member 12 by the connection cap 20, may be inserted into the retaining sheet 40 only if the connection between the inflator device 14 and the connection cap 20 is properly made. Otherwise, the inflator device 14 and / or the connection cap 20 would at least partially protrude from the base 32, and in particular from the storage cavity 36.

[0164] As previously anticipated, movement of the detection means 33 from its first configuration to its second configuration is designed to occur when the inflator device 14 is inserted into the retaining seat 40.

[0165] Similarly, if the inflator device is provided with a connecting means connected to the inflatable member, the movement of the detection means from its first configuration to its second configuration is designed to occur when the inflator device 14 with the connecting means is inserted into its retaining seat 40.

[0166] 3-19, the spacing means 38 is disposed near the retaining sheet 40 and is designed to contact the inflator device 14 when the inflator device 14 is inserted into the retaining sheet 40. In particular, when the spacing means comprises at least one L-shaped lever 39, the second arm 54 of the lever 39 is designed to contact the inflator device 14.

[0167] In particular, the contact between the inflator device 14 and the spacing means 38 is designed to essentially implement a cam and follower mechanism.

[0168] In particular, when the inflator device 14 is inserted into its retaining seat 40, the inflator device 14 contacts the second arm 54 of the lever 39. The outer surface of the inflator device 14 acts as a cam and the second arm 54 acts as a follower.

[0169] The force exerted by the inflator device 14 on the lever 39 may cause the second arm 54 to be pushed away from the inflator device 14 and its distal end 58 to be retracted into the base.

[0170] In particular, lever 39 can rotate about its pivot point 44 in a direction that is not blocked by counterpart 56. Lever 39 can thus reach the second configuration, allowing cover portion 34 to be properly secured to base 32.

[0171] When the inflator device 14 is removed from its retaining seat 40, the force exerted by the resilient means 48 disposed between the support member 42 and the lever 39 may cause the lever 39 to return to its first configuration.

[0172] The provision of counter portion 56 ensures that movement of lever 39 to a different configuration is not permitted which would allow cover portion 34 to abut base 32 if the cover is pressed against the base without inserting the inflator device into its retaining seat.

[0173] In fact, in this case, the stem 70 remains blocked in its first configuration by keeping the base and cover portions of the housing spaced apart.

[0174] When the spacing means 38 comprises at least one stem 70 and at least one rod 74 , the rod 74 is designed to contact the inflator device 14 .

[0175] In particular, again, the contact between the inflator device 14 and the spacing means 38 is designed to essentially implement a cam and follower mechanism.

[0176] In particular, when the inflator device 14 is inserted into its retaining seat 40, the inflator device 14 contacts the rod 74. The outer surface of the inflator device 14 acts as a cam and the rod 74 acts as a follower.

[0177] When the cover portion 34 is applied onto the base 32 due to the force exerted by the inflator device 14 on the rod 74 , the stem 70 moves along the T axis and is no longer positioned relative to the abutment portion 72 .

[0178] In particular, the assembly formed by the stem 70 and the rod 74 can thus reach the second configuration, allowing the cover portion 34 to be properly secured to the base 32 .

[0179] When the inflator device 14 is removed from its retaining seat 40, the force exerted by the resilient means 48 disposed between the support member 42 and the stem 70 may cause the stem 70 and rod 74 to return to their first configuration.

[0180] The provision of shoulder 45 on support member 42 ensures that stem 70 remains correctly positioned on support member 42. Furthermore, the positive fit between the rod and the hole provided in the shoulder of the support member ensures that rotation or other movement of stem 70 cannot be permitted when the cover is pressed onto the base without inserting the inflator device into its retaining seat.

[0181] In fact, in this case too, the lever 39 remains blocked in its first configuration by keeping the base and cover portions of the housing spaced apart.

[0182] As expected, detectors 80, 90, 100 are designed to detect the presence of inflator device 14 within its retaining seat, providing different feedback regarding spacing means 38. In particular, detectors 80, 90, 100 are designed to provide direct feedback that is not related to the interconnection of the cover portion to the base.

[0183] The feedback of the detectors 80, 90, 100 can be used to directly switch on the control unit or provide a visual or acoustic signal only when the detector is in its second configuration, as previously envisaged.

[0184] Preferably, the wearable protection device 10 may comprise a plurality of spaced apart detection means 33. Advantageously, the plurality of detection means 33 may comprise different types of detection means. For example, as shown in Figure 8, the detection means 33 may comprise two levers 39 arranged along the sides of the retainer sheet.

[0185] Alternatively, as shown in FIGS. 14 and 15, a lever 39 may be used in combination with the assembly formed by a stem 70 and a rod 74 .

[0186] When the housing 30 includes two or more spacing means 38, the spacing means 38 may be arranged to rotate along a single longitudinal axis L or to move along a single transverse axis T.

[0187] Alternatively, the spacing means 38 may be staggered along the longitudinal axis L or along the transverse axis T to better cooperate with the inflator device 14 .

[0188] The provision of multiple spacing means 38, for example two L-shaped levers 39 such as those shown in FIG. 8, is particularly useful when the inflator device 14 is secured to the inflatable member 12 by a connecting cap 20.

[0189] Indeed, in this case, the placement of the second L-shaped lever 39 spaced apart from the first L-shaped lever ensures greater safety. The first lever 39A may control the presence of the inflator device 14, while the second lever 39B may control the presence of the connection cap 20 (see, for example, FIG. 11).

[0190] As shown in FIG. 10, when only the inflator device 14 is properly inserted into the retaining seat 40, the first lever 39A is moved to its second configuration, and closure of the housing 30 will be prevented in either case by the presence of the second lever 39B, which is still in its first configuration due to the absence of the connecting cap 20.

[0191] Similarly, when only the connecting cap 20 is properly inserted into the retaining seat 40, the presence of the first lever 39A in its first configuration, resulting in the movement of the second lever 39B to its second configuration, will in any case prevent closure of the housing 30 due to the absence of the inflator 14.

[0192] Similarly, with reference to the embodiment of Figures 14 and 15, the lever 39 may be used to detect the presence of the inflator device 14, and the assembly formed by the stem 70 and rod 74 may be used to detect the presence of the connecting cap 20.

[0193] Only when both elements are properly received within retaining seat 40 will lever 39 and the assembly formed by stem 70 and rod 74 both be in the second configuration, allowing closure of housing 30.

[0194] Advantageously, the provision of spacing means 38 can be combined with sensing means 62, 64 arranged on opposite facing surfaces of base 32 and cover part 34 (see Figure 13).

[0195] The magnet 62 designed to cooperate with sensing means 62, 64, for example a proximity sensor 64, can advantageously send a signal when the cover portion 34 is positioned close to the base 32, where close means that the cover portion 34 is less than 1 cm from the base.

[0196] According to the foregoing disclosure, such a signal may only be emitted when the spacing means 38 is in its second configuration.

[0197] Thus, when the inflatable member 12 of the wearable protective device 10 is electrically activated, the signal emitted by the sensing means 62, 64 can be used to activate the system and switch the control unit 26 to an "on state," which can trigger the inflator device 14 as needed.

[0198] Similarly, when the inflatable member 12 of the wearable protective device 10 is mechanically activated, the sensing means 62, 64 may be designed to emit a visual or acoustic signal suitable to inform the user that the inflatable member 12 is suitable for proper inflation as required.

[0199] As anticipated, the present invention also relates to a method for safely activating the inflatable member 12 of the wearable protective device 10.

[0200] The method comprises: - providing a wearable protective device 10, the wearable protective device 10 comprising: i) at least one inflatable member 12 adapted to move between a rest state in which it is deflated and an operational state in which it is inflated; ii) at least one inflator device 14 designed to be coupled to the at least one inflatable member 12 and to inflate the at least one inflatable member 12 when the inflator device is triggered; and iii) a housing 30 designed to house the at least one inflator device 14; - verifying that at least one inflator device 14 and inflatable member 12 are properly coupled; - preventing triggering of the at least one inflator device if an improper coupling between the at least one inflator device and the inflatable member is identified; The checking step is carried out by detection means 33 provided within the housing 30 and designed to detect the presence of at least one inflator device within the housing 30 .

[0201] Preferably, when the wearable protective device 10 includes a control unit 26 designed to process data detected by the sensors 24 and to send a trigger signal to the inflator device 14 when a dangerous situation is identified, the detection means 33 is adapted to send, directly or indirectly, to the control unit 26, the presence of at least one inflator device in the housing.

[0202] Advantageously, the presence of the at least one inflator device may be indirectly transmitted to the control unit 26 by sensing means 62, 64 arranged between the base 32 and the cover portion 34 of the housing 30, said sensing means 62, 64 being associated with the detection means 33. In this case, the detection means 33 comprises spacing means 38 which may keep the base 32 and the cover portion 34 spaced apart when no inflator device is inserted into the housing 30.

[0203] Alternatively, the presence of at least one inflator device may be transmitted directly to the control unit 26 by the detection means 33, which comprises detectors 80, 90, 100 suitable for detecting whether an inflator device is present in the housing and transmitting corresponding feedback to the control unit 26.

[0204] At this point, it is clear how the wearable protective device 10 and the method of the present invention achieve the predetermined objectives.

[0205] The detection means 33 ensures that inflation of the inflatable bag occurs only if the inflator device is properly inserted into its housing and it is properly coupled to the inflator device.

[0206] When the detection means 33 includes spacing means 38 such as those shown in Figures 2-19, the spacing means ensures that the cover portion 34 and the base 32 of the housing 30 of the inflator device 14 can be secured only when the inflator device 14 is properly inserted into the housing 30.

[0207] If the inflator device 14 is missing or is not properly inserted within its retaining seat 40, the spacing means 38 will not be moved to its second configuration, and thus the base 32 and cover portion 34 will be spaced apart, preventing possible fixation of the cover portion 34 to the base 32.

[0208] In this way, further assistance is provided to the user during replacement of the inflator device, ensuring reliable and immediate feedback to the user as to the outcome of the replacement.

[0209] Also, if the detection means 33 comprises detectors 80, 90, 100 that can directly detect whether an inflator device is present in the housing, reliable feedback is provided.

[0210] With respect to the embodiments of the wearable protective device described above, those skilled in the art may make changes to the described elements and / or replace the described elements with equivalent elements in order to meet their particular requirements, without thereby departing from the scope of the appended claims.
