A seat for vehicles, comprising, a back of a seat, a seat cushion carrier rigidly connected with said back of said seat, a stationary seat frame, guide roller means mounting displaceably said seat in a vertical direction, a carrier spring means supporting said seat and comprising a coil spring containing an inclination variable and length variable spring leg, the latter having a lower foot side, a swinging pin connecting said spring leg at said foot side with said seat frame, a spindle mounted on said seat cushion carrier, a spindle nut operatively disposed on said spindle, said spring leg pivotally connected at its upper end with said spindle nut, and said spindle defining a lower spindle section, said spindle extending inclined to the horizontal in a direction transverse to said seat, such that said lower spindle section is disposed approximately vertically above said foot sided swinging pin of said spring leg.
Claim 3
Dependent Claim
84 words
The vehicle seat, as set forth in claim 5, wherein said guide roller means comprises three roller pairs provided on said seat cushion carrier, the latter carrying said spindle, first guides, two of said three roller pairs running in said first guides, the latter restraining said seat in the direction of movement of said vehicle, a second guide arranged between said first guides, and the third of said roller pairs running in said second guide, the latter restraining said seat in the transverse direction.
Claim 4
Dependent Claim
88 words
The seat, as set forth in claim 6, wherein said frame includes a back wall, said first guides comprise lateral guides including inwardly open double-edge formations of said back wall of said frame operatively connected with said seat cushion carrier, and said second guide comprises angle-formed guide rails equipped on said back wall of said frame in its center range for said third roller pair, thE latter constituting a middle pair of said three roller pairs, and said angle-formed guide rails restraining from movement in the transverse direction.
Claim 5
Dependent Claim
102 words
The vehicle seat, as set forth in claim 5, wherein said spring leg comprises an inner shorter pressure spring and an outer longer pressure spring disposed coaxially relative to each other, a joint foot sided counter bearing supporting one end of said springs, two tubes telescopically displaceable relative to each other and receiving said inner shorter of said pressure springs, said two tubes extend inside of said outer longer of said pressure springs, an additional outer telescopic tube having a bottom, and said outer longer pressure spring inserted in said additional outer telescopic tube and supported against said bottom of the latter.
