Abstract
Abstract A device for providing an illuminated indication of rapid deceleration of a vehicle. A biased momentum sensor moves against the biasing force when an appropriate magnitude of deceleration is experienced to establish a closed circuit and thereby illuminate a lamp. The biasing force imposed upon the momentum sensor is adjustable over a broad range while at the same time maintaining the gap distance between the cooperating contacts of the device constant. The contacts are so arranged as to provide for locking of the device in the illuminated condition in situations involving extremely abrupt deceleration. Sensing means may also be provided for providing an illuminated indication of an attempt to bring the vehicle carrying the sensor to an abrupt halt.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
Deceleration sensing means mounted upon a vehicle comprising: a hollow housing; a sensor mounted for reciprocal movement within said housing and being normally biased toward a first rest position; a first contact member movable with said sensor; a second contact member positioned within said housing and normally spaced from said first contact member when said sensor is in the rest position; means engaging said sensor for adjustably positioning the sensor within said housing to control the magnitude of the biasing force; said second contact being movable with said adjustable positioning means whereby the spacing distance between said first and second contacts remains constant regardless of the position of the adjustable mEans.
Claim 2
Dependent Claim
111 words
Deceleration sensing means mounted upon a vehicle comprising: a hollow housing; a sensor mounted for reciprocal movement within said housing and being normally biased toward a first rest position; a first contact member movable with said sensor; a second contact member positioned within said housing and normally spaced from said first contact member when said sensor is in the rest position; means engaging said sensor for adjustably positioning the sensor within said housing to control the magnitude of the biasing force; said second contact being movable with said adjustable positioning means whereby the spacing distance between said first and second contacts remains constant regardless of the position of the adjustable mEans.
Claim 3
Dependent Claim
78 words
The device of claim 1 wherein said second contact has at least a portion thereof lying in the path of movement of said first contact and is normally positioned to one side of said first contact; said second contact being resilient so as to be enabled to be deflected away from the path of movement of said first contact and to engage the opposite surface of said first contact when said sensor experiences deceleration of a predetermined magnitude.
Claim 4
Dependent Claim
40 words
The device of claim 1 further comprising a series circuit comprising a power source and a lamp coupled to at least one of said first and second contacts for illuminating said lamp upon engagement of said first and second contacts.
Claim 5
Dependent Claim
23 words
The device of claim 1 wherein said adjustable means further comprises means for mounting said second contact being threadedly engaged by said housing.
Claim 6
Dependent Claim
51 words
The device of claim 1 wherein said second contact is comprised of a pair of spring contacts; said adjustable means holding said spring contacts in a displaced manner; said adjustable means threadedly engaging said housing; said first contact having a substantially curved surface confronting said spring contacts for sliding engagement therewith.
Claim 7
Dependent Claim
83 words
The device of claim 1 wherein said second contact is comprised of a pair of spring contacts; said adjustable means holding said spring contacts in a displaced manner; said adjustable means threadedly engaging said housing; said first contact having a substantially curved surface confronting said spring contacts for sliding engagement therewith; said first contact being movable beyond the distal ends of said spring contacts for locking said first contact and said spring contacts in engagement when said sensor experiences a predetermined deceleration magnitude.
Claim 8
Dependent Claim
24 words
The device of claim 3 further comprising means coupled to said series circuit for causing said lamp to flash when said contacts are engaged.
Claim 9
Dependent Claim
28 words
The device of claim 1 wherein said second contact is comprised of a pair of contacts having inwardly bent edges for making sliding engagement with said first contact.
Claim 10
Dependent Claim
62 words
The device of claim 8 further comprising a pair of resilient stiffening means each positioned adjacent an associated one of said pair of contacts for providing additional contact pressure during operation thereof so as to greatly increase the operating life of the device and to increase the momentum required to attain a lock-in of the cooperating contacts and thereby prevent accidental lock-in.
Claim 11
Dependent Claim
135 words
A motion sensing device comprising: a hollow housing; a motion sensor mounted for reciprocating movement in said housing; bias means positioned between said sensor and a first end of said housing normally biasing said sensor away from the first end of said housing; a first contact mounted on the end of said sensor remote from the first end of said housing; an adjustable contact assembly mounted adjacent the second end of said housing and having a body portion and a second contact projecting generally outwardly from said body portion toward said housing first end; said first contact normally engaging said body portion and being disengaged from said second contact when at rest; said body portion being adjustably movable relative to said housing to adjust the biasing force imposed upon said sensor by said biasing means.
Claim 12
Dependent Claim
135 words
A motion sensing device comprising: a hollow housing; a motion sensor mounted for reciprocating movement in said housing; bias means positioned between said sensor and a first end of said housing normally biasing said sensor away from the first end of said housing; a first contact mounted on the end of said sensor remote from the first end of said housing; an adjustable contact assembly mounted adjacent the second end of said housing and having a body portion and a second contact projecting generally outwardly from said body portion toward said housing first end; said first contact normally engaging said body portion and being disengaged from said second contact when at rest; said body portion being adjustably movable relative to said housing to adjust the biasing force imposed upon said sensor by said biasing means.
Claim 13
Dependent Claim
77 words
A motion sensor comprising: a hollow housing; a sensor mounted for reciprocal movement within said housing and having a first contact secured thereto; means positioned within said housing for biasing said sensor in a first direction; second contact means including adjustable means normally engaging said sensor for adjustably selecting the rest position of said sensor while maintaining a constant spacing between said second contact means and said first contact regardless of the rest position of said sensor.
Claim 14
Dependent Claim
77 words
A motion sensor comprising: a hollow housing; a sensor mounted for reciprocal movement within said housing and having a first contact secured thereto; means positioned within said housing for biasing said sensor in a first direction; second contact means including adjustable means normally engaging said sensor for adjustably selecting the rest position of said sensor while maintaining a constant spacing between said second contact means and said first contact regardless of the rest position of said sensor.
