Description

Technical field

The present invention refers to an airbag garment and the use of such airbag garment.

Technical background

Airbag garments comprising an airbag that is inflatable by means of an integrated gas generator in the event of a detected accident are well known in the art. The typical user of such airbag garment is a cyclist, a motor cyclist, or a construction worker. It can also be a person with reduced balance capability. To be comfortable during its normal use, which in fact is a prerequisite for the airbag garment to be used as intended, it is essential that the garment is not perceived as being heavy or bulky. It should also be allowed to be worn together with an outer garment, such as a jacket or shirt, but also with gloves if necessary. When worn underneath an outer garment, the airbag garment will be hidden from the user's sight. This means that there is a problem of providing a visual, passive, communication between the airbag garment and the user. There is also a problem of providing an operative, active, communication between the airbag garment and the user. Non-limiting examples of a visual, passive, communication is battery status and if the airbag garment is powered or not, i.e., switched on or off. This can by way of example be made by one or more LEDs or via a display. A non-limiting example of an operative, active, communication, is the possibility for the user to switch the power on or off. There is hence a need to provide a more user-friendly airbag garment that is easy to use no matter if it is used as a stand-alone airbag garment or under an outer garment.

Summary

It is an object of the present invention to provide an airbag garment that allows an improved interaction and communication with the user, no matter if it is a passive or active communication, or a combination thereof.
Another object is to provide an airbag garment that is easy to use, no matter if it used as a stand-alone airbag garment or if used together with an outer garment.
Another object is to provide an airbag garment that is compatible with gloves. These and other objects that will be apparent from the following summary and description are achieved by an airbag garment, said airbag garment comprising an inflatable airbag, a gas generator arranged in communication with the inflatable airbag, a digital system operable connected to the gas generator, and a feedback unit being configured to indicate and/or control functionality of the digital system,
said feedback unit being attached to the airbag garment via an attachment member, said attachment member having a free length allowing the feedback unit to be detachably connected to the airbag garment itself, to another garment to be worn together with the airbag garment or across a user's hand, in a position remote from the digital system.
The attachment member may be one or more of a communication wire, a webbing or a cord.
The attachment member may be a communication wire, and the feedback unit may be operable connected to the digital system via the communication wire.
In the context of the present invention, the term "free length" is to be understood as the length of the webbing or cord as measured between its connection points to the feedback unit and the airbag garment. In case of a communication wire, it is to be understood as the length of the communication wire as measured between its connection points to the feedback unit and the digital system respectively.
By arranging a thus attached feedback unit, the feedback unit may be detachable arranged on the user's discretion in a suitable position where the user has a visual access to the feedback unit. The desired position may vary depending on a number of different parameters. As non-limiting examples, the desired position may vary depending on if the airbag garment is the only worn garment or if it is worn together with another garment, if the airbag garment or the another garment has long sleeves or not, the length of such sleeves, and also if the user is wearing gloves or not.
Further, since the feedback unit is connected via an attachment member, there is no risk of the feedback unit being lost.
Since the feedback unit is attached to the airbag garment, the user of the airbag garment will have an easy access to the system status when the airbag garment is worn and also no matter if the airbag garment is worn alone or in combination with another garment. The airbag garment may by way of example be configured as a jacket, a shirt or an overall, but also as a vest or a harness.

In the context of the invention, the term "passive" is to be understood as a visual, tactile or audial communication from the digital system 8 to the feedback unit 15. It can also be a combination of two or more of a visual, tactile and audial communication. A non-limiting example of a visual communication is one or more LEDs or an LCD indicating battery status. A non-limiting example of a tactile communication is a vibrator indicating low power of the battery. A non-limiting example of an audial communication is a speaker indicating a low power of the battery.
In the context of the invention, the term "active", is to be understood as an operable communication, where the user of the airbag garment is allowed to actively set the digital system 8. As a non-limiting example this may be turning the power on or off.
The communication wire 16 has a free length that allows the feedback unit 15 to be detachably connected to the airbag garment 100 itself, to another garment 200 to be worn together with the airbag garment 100 or across a user's hand, in a position remote from the digital system 8. In the context of the present invention, the term "free length of the communication wire" is to be understood as the length of the communication wire 16 as measured between its connection points to the feedback unit 15 and to the digital system 8 respectively.
The feedback unit 15 may be detachable arranged on the user's discretion in any suitable position where the user has a visual access to the feedback unit 15. The desired position may vary depending on a number of different parameters. As non-limiting examples, the desired position may vary depending on if the airbag garment 100 is the only worn garment or if it is worn together with another garment 200, if the airbag garment or the another garment 200 has long sleeves 101 or not, the length of such sleeves 101, and also if the user is wearing gloves 300 or not.
The communication wire 16 is routed in a channel 17 in the airbag garment 100. The channel 17 extends from a position in the airbag garment 100 adjacent the position of the digital system 8 to a hem 106 of the airbag garment 100 or to a free end of a sleeve 101 of the airbag garment 100. The hem 106 may be any hem of the airbag garment 100. The hem 106 may by way of example be along a lower frontal or side edge portion of the airbag garment 100, along a frontal zipper in the case the airbag garment 100 is a jacket, or adjacent a cuff 103 of the airbag garment 100 or adjacent a wrist unit 104 of the airbag garment 100.
The channel 17 is disclosed in Fig. 1 as a channel that extends from the digital system 8 that is disclosed as being arranged in the neck portion of the airbag garment 100 and along one of the long sleeves 101 towards the cuff 103 that is arranged in the end of the sleeve 101. The channel 17 may be a sewn channel or a channel that is mounted to a surface layer of the airbag garment 100, e.g., by welding or adhesive. The channel 17 may be arranged on an exterior surface layer of the airbag garment 100 or on an inner surface layer, such as on an inner liner of the airbag garment 100.

Accordingly and in summary, an airbag garment is provided that comprises an inflatable airbag, a gas generator arranged in communication with the inflatable airbag, a digital system operable connected to the gas generator, and a feedback unit being configured to indicate and/or control functionality of the digital system. The feedback unit is attached to the airbag garment via an attachment member. The attachment member has a free length allowing the feedback unit to be detachably connected to the airbag garment itself, to another garment to be worn together with the airbag garment or across a user's hand, in a position remote from the digital system. This allows the user of the airbag garment to have an easy access to the system status when the airbag garment is worn. The feedback unit may be positioned at the user's discretion where the user has easy access to the information presented by the feedback unit. This applies no matter if the airbag garment is worn alone or in combination with another garment on top of the airbag garment. Depending on the type of feedback unit, the user can either be passively presented with information from the digital system, or be allowed to actively operate the digital system, e.g., turning it on/off.
The airbag garment has been disclosed and exemplified as a shirt or jacket with long sleeves. The principle with a channel receiving the communication wire of the feedback unit is equally applicable to other garments, such as a vest, an overall or a harness. Correspondingly, the another garment must not be a shirt, a jacket or a glove, but may be a bag or the like.
