Description
Description A. Title: Helmet with Inflatable Airbag B. Technical Field of the Invention The invention relates to a helmet with Inflatable airbag for cyclist's head protection, and more specifically to an airbag apparatus for cyclist head protection which absorbs and reduces an impact on a cyclist's head at the event of a collision with a hard surface.
C. Description of Background prior Art Prior to filing the patent, the initial design was posted on Kickstarter in a search to raise money to complete the initial porotype. Photos of a model are shown on the website under the name "HelmetWorX" and is based in Halifax, Nova Scotia. There were five views of the Helmet with Inflatable Airbag included on Kickstarter. Each Figure was a picture taken of the non-functioning prototype fabricated out of an old helmet garbage bags to present the intention of the concept. The Kickstarter campaign commenced end of day 31 Oct 2017.
D. Background of the Invention Helmets are worn in sports (e.g., football, hockey and cycling) and other activities (e.g., construction work, military operations and race car driving, etc.) to protect their wearers head against potential injuries. Helmets typically comprise of a rigid outer shell and inner padding to absorb energy when impacted.
The invention relates to a helmet and inflatable airbag system, and more particularly, to an airbag safety system and, even more particularly, a helmet and inflatable airbag system employed as a lifesaving system to enable a person who is a cyclist using such a system to survive a crash or a crash involving head trauma.
Protective headgear for use by bicyclists is required to address a number of needs.
Providing proven protection of the cyclist's head form trauma injury following an accidental impacting fall to the ground, notably when the bicycle falls and rolls at high speed on the ground.
More particularly, such a protective headgear will be equipped with an inflatable airbag, such a system will be activated automatically by a sensor to provide protection to the wearer enabling the user to survive a crash involving head trauma.
The systems comprising the helmet with inflatable airbag are designed to prevent head trauma to the wearer and to enable the victim to survive a crash with the fewest possible injuries to the head when wearing a helmet that incorporates such a system. When activated, the helmet deploys a horizontally elongated airbag around the head of the user. The airbag and helmet provide unobstructed vision and freedom of movement, even with the inflated airbag, allows the wearer to survive a crash or situation involving head trauma. Each of the systems known in the field of technology, including the systems relies upon a onetime use container of compressed gas (such as air or nitrogen) to inflate the airbag.
Page lot 9 The helmet should be so constructed as to be resistant to fragmentation after a violent impact, as many high-speed falls of cyclist's involve multiple impacts to the head of the cyclist.
Helmet should be effective in protecting the cyclists head from impact trauma from a first ground impact, but remains effective in protecting against secondary impacts when the helmet goes through fracturing, fragmenting or the deformation.
Due to the size and wright constraints of helmets, the airbag and compressed gas system using cylinders/cartridges, the available volume to which the airbag is inflated is listed during release of the compressed gas. Systems employing compressed gas/cartridges are additionally adversely affected by the weight of such as system. The solution is in a reduction of the amount of pressurized gas required to inflate he airbag.
The helmet provides suitable shielding from sun stroke and protects the wearer from the weather and its effects. Cyclist may suffer from sun stroke is imminent because of the incoming wind that circulates over the cyclist's face as the bicycle and cyclist moves forward. The helmet will also provide proper air ventilation of the head. The weight of the helmet is minimized, to decrease fatigue of the neck of the cyclist as this would be a safety hazard in compromising the attention span of the cyclist when to surrounding vehicles and potential hazards when on the road.
Helmets currently in use do not provide for an optimum mix of these desirable parameters. Various types of impacts are possible. For example, a helmet may be subjected to linear and rotational impact causing serious injuries such as concussions, subdural hemorrhage and nerve damage. Helmets are able to provide decent protection but they are deficient against high energy impacts caused by cycling. This is clearly problematic given the severity of head injuries caused by cycling. Existing helmets are not always adequate or optimal, for these reasons, there is a need for improvements directed to providing helmets with enhanced impact protection with today's technology.

However, it is to be understood that this description is repeated for the purpose of enhancing an understanding of the invention and not to limit it to such particular embodiments and methods.
The helmet 2 protects various regions of the wearers head 1. As shown in Figures 1 and
2. The wearers head compromises a front region FR, a top region TR, left and right side LR and RS and a back region BR and the neck region NR. The FR includes the forehead, front top part of the wearers head, mouth area and the front region of the wearers head FR.
The LR and RR
include the area above the wearers ears. The BR is opposite to the FR and includes the rear upper part of the head. The neck region NR corresponds to the region of the neck under the head of the wearer. As shown in Figure 3, the right side of helmet RSH and left side of helmet LSH
serve to show the direction of the helmet.
Figures 5 and 6 show an example of a helmet with airbag deployed 3 for protecting a head 1 of wearer in accordance with an embodiment of the invention. In this embodiment, the helmet 2 is a sports helmet for protecting the head 1 of the wearer who is a general sports player.
More particular, in this embodiment, the helmet 2 is a bicycle helmet with airbag 3 for protecting the head 1 of the wearer who is a cyclist. In other embodiments, the helmet may be any other type of helmet for other sports such as horseback riding, motorcycling, etc.
in which protection against head injury is desired.
Page 4 of 9 Although in embodiments considered above the helmet 2 is a cyclist helmet for protecting the head of a cyclist, in other embodiments, a helmet constructed using the principles described in respect of the helmet may be another type of sport helmet. For instance, a helmet constructed using the principle described herein in respect of the helmet 2 may be for protecting the head of the wearer of another sport in which significant impact forces are due to player on player or player on object contact. For example, in one embodiment, protecting the head of a Luge, ski jumping, horseback riding, older people with mental health issues and stability issues.
Furthermore, a helmet constructed using principles described therein in respect of the helmet 2 may be for protecting the head of the wearer in a sport other then a contact sport. Any feature of any embodiment discussed herein may be combined with any feature of any other embodiment discussed herein in some examples of implementation.
Fig 5 and 6 illustrates an airbag system 3 according to the invention incorporated with a helmet 2, with a helmet in a deployed i.e. inflated configuration. The helmet provides the structure for supporting various components of the airbag system seen in Fig 7, as further described in connection with Fig 5 and 6. The helmet includes a harness system to hold the helmet to the head of the wearer and provide rigidity and will be attached to the base of the helmet 9, although the harness is not shown, it is not limited to a specific embodiment.
In alternative embodiments, not shown, the airbag system of the invention can be incorporated with any various helmets as an add on. For example, a normal helmet with the addition of an airbag mechanism to convert the helmet into an airbag helmet.
Although not shown with further particularity, the uninflated airbag can be stored in the airbag storage compartment 4 prior to activation and released from the compartment upon inflation of the airbag system.
To facilitate the inflation of the airbag with 100% compressed gas, the helmet will include a compressed gas cylinder 5 in the helmet body. The air is fed through the main compartment of the airbag to fil the airbags volume (10) Fig 7 illustrates a conduit 6 providing a compressed gas passageway for output to the airbag being held within the helmet for inflation 4.
The invention encompassed other forms of air movement device for achieving the objectives of the invention, particularly that of fully inflating an airbag volume of less then 10L with in a predetermined time period. For example, ducted fan blower, centrifugal fan or turbine, rotary pump, gear pump, blower fan and all possibilities with the scope of the invention. These are commonly referred to as air movement devices and can be multi stage devices.
The electric power supply to the compressed gas is in the form of a battery 7, such as NiCad battery or similar and the controller and valve device 8 that provides the activation of the airbag through the use of a valve or similar device.
Although the airbag illustrated in the drawings such as Fig 5 and 6 extends around from the rear BR and NR and along both sides LS, RS and the FR of the wearer of the helmet 2, the invention is not limited to such particular shape can be suitably practiced with other shapes. The invention can be suitably practiced with a pair of airbags. Further, the total volume of the airbag could be approximately 15 L, although the columns can be larger if desired, such as within range Page 5 of 9 of approximately 25L, in as much it would not appear to be a large increment on weight of the system for utilizing airbags with a larger volume.
In operation, when the wearer becomes involved in a crash or impact, the sensor manipulates the valve resulting in a signal being sent from the controller and valve device 8 enabling compressed gas or as embodied gas being released through the passageway 6 to the output airbag for inflation of the helmet with airbag 3. The air is distributed through the main channel for the airbag (10) to completely fill the volume of the airbag.
According to the particular embodiment of the invention, the compressed gas or ambient air is pumped into the airbag for a predetermined time fully inflating the airbag 3. This could accommodate variations in ambient conditions such as including variations in temperature and pressure which could affect a predetermined full inflate time. Kinetic energy will be dissipated in the helmet 2 if the airbag 3 fails to be inflated enabling the wearer 1 of the helmet to remain protected. Successive impacts on the helmet with 3 or without 2 the airbag inflated will have the kinetic energy absorbed without compromising the shielding capabilities of the helmet on the wearer. The helmet will remain integral even after a number of impacts.
In a simplified embodiment according to the invention, the airbag system includes in addition to the air bag 3, air movement device or compressed air 5, sensor and valve 8 and power source 7 and on/off switch 9 whereby when the wearer becomes involved in a crash or accident, the sensor automatically activates the valve 8 thereby inflating the airbag 3.
If the airbag fails to activate, the wearer remans protected by use of the helmet 2.
The helmet 2 defines a cavity for receiving the wearers head 1 to protect the wearers head when the helmet 2 is impacted (e.g. when the helmet 2 hits the roadway or an object during an impact involving the cyclist). In this embodiment, the helmet 2 is designed to provide redundant protection against various types of impacts. More particularly, in this embodiment, the helmet is designed to provide protection against a linear impact in which an impact force is generally oriented to pass through a center of gravity of the wearers head and imparts a linear acceleration to the wearers head 1. In addition, in this embodiment, the helmet 2 is designed to provide protection against a rotational impact in which force imparts an angular acceleration to the wearer's head 1. The helmet 2 is also designed to protect against high-energy impacts and low-energy impacts.
In response to an impact, the helmet 2 absorbs energy from the impact to protect the wearer's head 1. Notably, in this embodiment, as further discussed below, the airbag of the helmet absorbs the impact in response to an impact on the helmet. This can enhance the protection of the wearers head 1. For example, this may provide protection against rotational impacts, thereby reducing rotational energy transmitted to the wearers head 1 and therefore, an angular acceleration of the wearers head. In this embodiment, the helmet 2 comprises an outer shell 11 that starts above the airbag storage compartment 4, airbag 3 and inner padding for added protection and comfort not shown with a specific embodiment. The helmet 2 also comprises a chinstrap not shown in any specific embodiment for securing the helmet 2 to the wearers head 1.
Page 6 of 9 The outer shell 11 provides additional strength to the cyclist helmet 2. To that end, the shell will be made of a rigid material. For example, in various embodiments, the outer shell may be of thermoplastic material such as polyethylene (PE), polyamide (nylon), polycarbonate or thermosetting resin or any other suitable material. In this embodiment, the shell 11 comprises a plurality of ventilation holes, allowing air to circulate around the wearers head 1 for added comfort and ventilation. The ventilation holes not shown in a specific embodiment may be implemented in various means. For example, in other embodiments, the holes may be rectangular of circular in the shell of the helmet 11. The shell and inner padding disposed between the outer shell and the wears head 1 in use to absorb the energy and the airbag to absorb the majority or bulk of the impact energy transmitted to the wearer head when the helmet is impacted. Materials of the helmet can be reinforced with other materials not mentioned.
For example, in this embodiment, the airbag 3 may be a material such as but not limited to thermoplastic material, polycarbonate, nylon, acylonitire butadiene styrene (ABS), polyamide (PA), glass or carbon reinforced polypropylene (PP) and or any other suitable material. In this embodiment, the helmet is deformable 2 (i.e. chanabgle in configuration) to allow the helmet to move in response to the impact on the helmet 2. More particularly, in this embodiment, the helmet comprises a material that allows for deformation of the helmet. For example, in some embodiments, the material of the helmet may have an elastic modulus of no more than 150 GPa, in some cases nore more then 100 GPA, in some cases no more 50 GPa, in some cases no more then 5 GPa, n some cases no more then 1 GPA and in some cases even less.
For instance, some embodiments, the material of the helmet may comprise a thermoplastic material, polycarbonate, nylon, acylonitire butadiene styrene (ABS), polyamide (PA), glass or carbon reinforced polypropylene (PP) and or any other suitable material.
Examples of suitable thermoplastic materials include rubber, high density VN
foam, high density PE foam.
Although various embodiments and examples have been presented, this aim for the purpose of describing, but not limiting, the invention. Various modification and enhancements will become apparent to those of ordinary skill in the art are with in the scope of the invention, which is defined by the claims.
Finally, although the invention has been described with reference to particular means, structures, materials and embodiments, it is to be understood that the invention isn't limited to the particular explicitly disclosed and extends to all equivalents wit the scope of the claims. In addition to the foregoing, the invention disclosed herein with reference to exemplary embodiments suitably may be practiced in the absence of any element which is not specialty dsocilied herein.

Although not shown with further particularity, the uninflated airbag can be stored in the airbag storage compartment 4 prior to activation and released from the compartment upon inflation of the airbag system.
To facilitate the inflation of the airbag with 100% compressed gas, the helmet will include a compressed gas cylinder 5 in the helmet body. The air is fed through the main compartment of the airbag to fil the airbags volume (10) Fig 7 illustrates a conduit 6 providing a compressed gas passageway for output to the airbag being held within the helmet for inflation 4.
The invention encompassed other forms of air movement device for achieving the objectives of the invention, particularly that of fully inflating an airbag volume of less then 10L with in a predetermined time period. For example, ducted fan blower, centrifugal fan or turbine, rotary pump, gear pump, blower fan and all possibilities with the scope of the invention. These are commonly referred to as air movement devices and can be multi stage devices.
The electric power supply to the compressed gas is in the form of a battery 7, such as NiCad battery or similar and the controller and valve device 8 that provides the activation of the airbag through the use of a valve or similar device.

The invention can be suitably practiced with a pair of airbags. Further, the total volume of the airbag could be approximately 15 L, although the columns can be larger if desired, such as within range Page 5 of 9 of approximately 25L, in as much it would not appear to be a large increment on weight of the system for utilizing airbags with a larger volume.
In operation, when the wearer becomes involved in a crash or impact, the sensor manipulates the valve resulting in a signal being sent from the controller and valve device 8 enabling compressed gas or as embodied gas being released through the passageway 6 to the output airbag for inflation of the helmet with airbag 3. The air is distributed through the main channel for the airbag (10) to completely fill the volume of the airbag.
According to the particular embodiment of the invention, the compressed gas or ambient air is pumped into the airbag for a predetermined time fully inflating the airbag 3. This could accommodate variations in ambient conditions such as including variations in temperature and pressure which could affect a predetermined full inflate time. Kinetic energy will be dissipated in the helmet 2 if the airbag 3 fails to be inflated enabling the wearer 1 of the helmet to remain protected. Successive impacts on the helmet with 3 or without 2 the airbag inflated will have the kinetic energy absorbed without compromising the shielding capabilities of the helmet on the wearer. The helmet will remain integral even after a number of impacts.
In a simplified embodiment according to the invention, the airbag system includes in addition to the air bag 3, air movement device or compressed air 5, sensor and valve 8 and power source 7 and on/off switch 9 whereby when the wearer becomes involved in a crash or accident, the sensor automatically activates the valve 8 thereby inflating the airbag 3.

For example, in various embodiments, the outer shell may be of thermoplastic material such as polyethylene (PE), polyamide (nylon), polycarbonate or thermosetting resin or any other suitable material. In this embodiment, the shell 11 comprises a plurality of ventilation holes, allowing air to circulate around the wearers head 1 for added comfort and ventilation. The ventilation holes not shown in a specific embodiment may be implemented in various means. For example, in other embodiments, the holes may be rectangular of circular in the shell of the helmet 11. The shell and inner padding disposed between the outer shell and the wears head 1 in use to absorb the energy and the airbag to absorb the majority or bulk of the impact energy transmitted to the wearer head when the helmet is impacted. Materials of the helmet can be reinforced with other materials not mentioned.
For example, in this embodiment, the airbag 3 may be a material such as but not limited to thermoplastic material, polycarbonate, nylon, acylonitire butadiene styrene (ABS), polyamide (PA), glass or carbon reinforced polypropylene (PP) and or any other suitable material. In this embodiment, the helmet is deformable 2 (i.e. chanabgle in configuration) to allow the helmet to move in response to the impact on the helmet 2. More particularly, in this embodiment, the helmet comprises a material that allows for deformation of the helmet. For example, in some embodiments, the material of the helmet may have an elastic modulus of no more than 150 GPa, in some cases nore more then 100 GPA, in some cases no more 50 GPa, in some cases no more then 5 GPa, n some cases no more then 1 GPA and in some cases even less.
