Abstract
Abstract A vehicle seat and a support therefor. The vehicle seat is supported by an air-spring assembly which yields when the driver or a passenger occupies the seat. The air-spring is capable of having its natural frequency adjusted, and this adjustment is brought about by way of swing-lever which is pivotally connected at one end to the frame of the seat and which is directly connected to the air-spring at a location situated at a distance from the pivotal connection to the seat which determines the length of one lever arm. A fulcrum member is shiftable along the swing-lever to a selected location which will determine a second lever arm. The ratio of the first to the second lever arm determines the natural frequency of the air-spring.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
In a vehicle, a support, a seat, air-spring means supporting said seat, said air-spring means having a first part thrusting against the seat and a second part thrusting against the support, and aDjustable means interposed between the second part of the air-spring means and the support for adjusting the natural frequency of the air-spring means, said adjustable means comprising a swing lever, means pivotally connecting the swing lever at one end to the seat, the second part of the air-spring means being fixedly connected to the swing lever, a lever supporting, fulcrum means disposed on the seat support and adjustably spaced from the pivotal connecting means, means for adjusting the position of the swing lever supporting fulcrum means longitudinally of the swing lever, and means for guiding the seat for movement along a fixed path toward and away from the seat support, said path being unaffected by the adjustment of said swing lever.
Claim 2
Dependent Claim
153 words
In a vehicle, a support, a seat, air-spring means supporting said seat, said air-spring means having a first part thrusting against the seat and a second part thrusting against the support, and aDjustable means interposed between the second part of the air-spring means and the support for adjusting the natural frequency of the air-spring means, said adjustable means comprising a swing lever, means pivotally connecting the swing lever at one end to the seat, the second part of the air-spring means being fixedly connected to the swing lever, a lever supporting, fulcrum means disposed on the seat support and adjustably spaced from the pivotal connecting means, means for adjusting the position of the swing lever supporting fulcrum means longitudinally of the swing lever, and means for guiding the seat for movement along a fixed path toward and away from the seat support, said path being unaffected by the adjustment of said swing lever.
Claim 3
Dependent Claim
22 words
The combination of claim 1 and wherein a three-way valve means coacts with said air-spring means for adjusting the air content thereof.
Claim 4
Dependent Claim
52 words
The combination of claim 1 and wherein said fulcrum means includes a block shiftable by the adjusting device along the swing-lever, and a roller rotatably carried by said block and engaged by said swing lever so that the point of engagement between said roller and swing-lever determines the location of the fulcrum.
Claim 5
Dependent Claim
44 words
The combination of claim 3 and wherein the adjusting device includes a rotary threaded spindle having a threaded connection with said block and extending in a direction generally parallel to said swing-lever for moving said block and said roller therewith longitudinally along said lever.
Claim 6
Dependent Claim
55 words
The combination of claim 1 and wherein a linkage means is operatively connected with said seat and a valve means is operatively connected with said linkage means to coact with the latter for determining the static elevation of the seat, said linkage means including a link assembly provided with a means for adjusting its length.
Claim 7
Dependent Claim
65 words
The combination of claim 5 and wherein said link assembly includes an elongated rod having a threaded end portion and a nut threaded onto said threaded end portion of said rod, the means for adjusting the length of the link assembly including a means operatively connected to the latter for providing relative rotary movement of the nut and rod, one with respect to the other.
Claim 8
Dependent Claim
55 words
The combination of claim 6 and wherein a bearing is swingably connected to said seat for free pivotal movement relative thereto and surrounds and carries the nut to support the latter for rotary movement while preventing axial movement thereof, so that upon turning of said nut the length of the link assembly will be adjusted.
