Abstract
Abstract The tiltable steering mechanism is comprised of a first bracket adapted to be fixed to the vehicle body and a second bracket rotatably supporting the upper portion of the steering column pivotally connected to the first bracket. An infinitely adjustable latch mechanism is provided for continuously adjusting the angle between the first and second brackets. The latch mechanism is separable to permit a tilt-away operation in which the steering mechanism is tilted quickly to the upper limit to facilitate ingress and egress from the vehicle. Upon subsequent lowering of the steering mechanism, the latch mechanism will automatically re-engage at the previously adjusted position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A tiltable steering mechanism comprising a first bracket adapted to be secured a vehicle body, a second bracket for rotatably supporting a steering shaft pivotally mounted on said first bracket, a sub-bracket secured to one side of said first bracket and having pin means at one end thereof, a first pivot pin secured to second bracket substantially above said pin means, a first locking lever pivotally mounted on said first pivot pin and having an elongated slot slidably engageable with said pin means, a tilt lever pivotally mounted on said first pivot pin, a second pivot pin secured to said tilt lever in spaced relation to said first pivot pin, a second locking lever pivotally supported on said second pivot pin, complementary locking means on said first and second locking levers for normally holding said tilt lever adjacent said first locking lever and latch means adjustably mounted on said tilt lever for movement toward and away from said first pivot pin and engageable with said pin means to hold said second bracket in adjusted position relative to said first bracket.
Claim 2
Dependent Claim
180 words
A tiltable steering mechanism comprising a first bracket adapted to be secured a vehicle body, a second bracket for rotatably supporting a steering shaft pivotally mounted on said first bracket, a sub-bracket secured to one side of said first bracket and having pin means at one end thereof, a first pivot pin secured to second bracket substantially above said pin means, a first locking lever pivotally mounted on said first pivot pin and having an elongated slot slidably engageable with said pin means, a tilt lever pivotally mounted on said first pivot pin, a second pivot pin secured to said tilt lever in spaced relation to said first pivot pin, a second locking lever pivotally supported on said second pivot pin, complementary locking means on said first and second locking levers for normally holding said tilt lever adjacent said first locking lever and latch means adjustably mounted on said tilt lever for movement toward and away from said first pivot pin and engageable with said pin means to hold said second bracket in adjusted position relative to said first bracket.
Claim 3
Dependent Claim
71 words
A tiltable steering mechanism as set forth in claim 1 further comprising shaft means rotably mounted in said tilt lever, complementary screw-threaded means on said shaft means and said latch means engageable with each other and means for rotating said shaft means for adjustably moving said latch along said shaft means while engaged with said pin means for continuously adjusting the position of said second bracket relative to said first bracket.
Claim 4
Dependent Claim
86 words
A tiltable steering mechanism as set forth in claim 2 wherein said means for rotating said shaft means is comprised of a knob secured to said shaft for rotation therewith and longitudinally movable lengthwise of said shaft adjacent one end, means for limiting sliding movement of said knob, spring means normally biasing said knob away from said latch means and complementary engageable means on said second locking lever and said knob for holding said second locking lever in unlocked position relative to said first locking lever.
Claim 5
Dependent Claim
40 words
A tiltable steering mechanism as set forth in claim 3 further comprising spring means operatively associated with said tilt lever and said second locking lever for normally biasing said second locking lever into locking engagement with said first locking lever.
Claim 6
Dependent Claim
59 words
A tiltable steering mechanism as set forth in claim 1 further comprising spring means operatively connected to said tilt lever and said second bracket for normally biasing said latch means against said pin means to automatically bring said latch means into locking engagement with said pin means upon downward tilting movement of said second bracket after a tilt-away operation.
