Abstract
Abstract A helmet with turn signal indicator for motorcycle riders and like applications includes a pair of lamps respectively disposed on left-hand and right-hand sides of the helmet body, and head tilt switches responsive to momentary tilting of the wearer's head in a given direction for selectively energizing the lamp on the corresponding helmet side. The lamps are driven by flasher holding circuits which may be selectively extinguished by rearward tilting of the wearer's head. Fiber optics extend within the helmet from adjacent the lamps to above the wearer's eyes to indicate operation to the wearer.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, first means including first inertia switch means carried by said helmet so as to be responsive to tilting of a wearer's head to either lateral side to initiate periodic energization of the said light emitting means on the same said lateral side for indicating an intent to turn in the corresponding lateral direction, and second means including second inertia switch means disposed and oriented with said helmet so as to be responsive to tilting of the wearer's head in the rearward direction for terminating said periodic energization.
Claim 2
Dependent Claim
115 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, first means including first inertia switch means carried by said helmet so as to be responsive to tilting of a wearer's head to either lateral side to initiate periodic energization of the said light emitting means on the same said lateral side for indicating an intent to turn in the corresponding lateral direction, and second means including second inertia switch means disposed and oriented with said helmet so as to be responsive to tilting of the wearer's head in the rearward direction for terminating said periodic energization.
Claim 3
Dependent Claim
51 words
The helmet set forth in claim 1 wherein said first means include flasher holding circuit means responsive to momentary tilting of the wearer's head in either direction and resulting momentary activation of said first inertia switch means for continuing said periodic energization after the wearer's head is returned to vertical orientation.
Claim 4
Dependent Claim
39 words
The helmet set forth in claim 2 wherein said flasher holding circuit means includes means for periodically energizing both of said light emitting means in response to tilting of the wearer's head to one side and then the other.
Claim 5
Dependent Claim
31 words
The helmet set forth in claim 2 wherein said first inertia switch means includes first and second inertia switches oriented at opposite acute angles to the lateral dimension of said helmet.
Claim 6
Dependent Claim
35 words
The helmet set forth in claim 2 further comprising light transmitting means extending through said helmet from adjacent each said light emitting means to a position adapted to be disposed adjacent to the wearer's eyes.
Claim 7
Dependent Claim
38 words
The helmet set forth in claim 2 further comprising means carried on and visible from the rear of said helmet to enable an observer from the rear to distinguish between left and right lateral sides of said helmet.
Claim 8
Dependent Claim
83 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, means operable by the wearer of said helmet for selectively energizing and de-energizing said light emitting means, and light transmitting means extending within said helmet from each said light emitting means to a position adapted to be disposed adjacent to the wearer's eyes for indicating to the wearer operation of each said light emitting means.
Claim 9
Dependent Claim
83 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, means operable by the wearer of said helmet for selectively energizing and de-energizing said light emitting means, and light transmitting means extending within said helmet from each said light emitting means to a position adapted to be disposed adjacent to the wearer's eyes for indicating to the wearer operation of each said light emitting means.
Claim 10
Dependent Claim
18 words
The helmet set forth in claim 7 wherein said light transmitting means comprises first and second optical fibers.
Claim 11
Dependent Claim
120 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, first means including first inertia switch means carried by said helmet so as to be responsive to tilting of a wearer's head in one lateral direction to initiate periodic energization of the said light emitting means on one lateral side of said helmet for indicating an intent to turn in said one lateral direction, and second means including second inertia switch means disposed and oriented within said helmet so as to be responsive to tilting of the wearer's head in a direction other than said one direction for terminating said periodic energization.
Claim 12
Dependent Claim
120 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, first means including first inertia switch means carried by said helmet so as to be responsive to tilting of a wearer's head in one lateral direction to initiate periodic energization of the said light emitting means on one lateral side of said helmet for indicating an intent to turn in said one lateral direction, and second means including second inertia switch means disposed and oriented within said helmet so as to be responsive to tilting of the wearer's head in a direction other than said one direction for terminating said periodic energization.
Claim 13
Dependent Claim
112 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, first means including first inertia switch means carried by said helmet so as to be responsive to tilting of a wearer's head in one lateral direction to initiate periodic energization of the said light emitting means on one lateral side of said helmet for indicating an intent to turn in the corresponding lateral direction, and second means including second inertia switch means disposed and oriented within said helmet so as to be responsive to tilting of the wearer's head for terminating said periodic energization.
Claim 14
Dependent Claim
112 words
In a helmet for motorcycle riders and like applications, a turn signal indicator comprising first and second light emitting means disposed on opposite lateral sides of said helmet, first means including first inertia switch means carried by said helmet so as to be responsive to tilting of a wearer's head in one lateral direction to initiate periodic energization of the said light emitting means on one lateral side of said helmet for indicating an intent to turn in the corresponding lateral direction, and second means including second inertia switch means disposed and oriented within said helmet so as to be responsive to tilting of the wearer's head for terminating said periodic energization.
