Seat construction

Claim 2

In a seat, particularly a vehicle seat, a combination comprising a support element; a seat element above said support element; and means for adjusting the position of said elements relative to one another, comprising an elongated strap connected to said seat element, a bracket of substantially U-shaped configuration having a bight and two arms extending transversely of said bight substantially in the same direction and bounding with said bight an open side of said bracket, one of said arms having a length substantially corresponding to that of said strap and being pivotally connected to the latter, said bracket being mounted on said support element for pivoting about an axis, and means for pivoting said bracket about said axis and including an elongated lever extending away from said open side and having longitudinally spaced ends one of which is pivotally connected to the other arm of said bracket and the other of which is mounted in said seat element for shifting in a substantially horizontal plane between, and for arresting in a selected one of a plurality of positions.

Claim 3

A combination as defined in claim 1, wherein said seat element includes a frame; and wherein the length of said other arm of said bracket corresponds substantially to the height of said frame.

Claim 4

A combination as defined in claim 1, wherein said one end of said lever is offset relative to the plane of said lever.

Claim 5

A combination as defined in claim 1, wherein said strap is fixedly connected to said seat element.

Claim 6

A combination as defined in claim 1, wherein said strap is pivoted to said seat element.

Claim 7

A combination as defined in claim 5; and further comprising a stabilizing rod extending between and pivoted to said seat element and said bracket respectively.

Claim 8

A combination as defined in claim 1, wherein said lever is provided with a pin in the region of said seat element, said seat element having a portion formed with a slot in which said pin is slidably received; and further comprising a spring having one fixed end and another end connected to said pin so as to urge the same to move in one direction in said slot.

Claim 9

A combination as defined in claim 7, wherein said portion of said seat element is a plate formed with teeth along said slot and pivotably mounted on said seat element, said teeth being engageable with said pin for arresting the same against sliding movement in said slot.

Claim 10

A combination as defined in claim 1, wherein said adjusting means comprises an additional strap, an additional bracket, and an additional lever all similar to the first-mentioned strap, bracket and lever but located at a side of said seat element opposite the one where the first-mentioned strap, bracket and lever are located; and further comprising a shaft fixedly connected with said first-mentioned and additional brackets.

Claim 11

In a seat, particularly a vehicle seat, a combination comprising a support element; a seat element above said support element; and means for adjusting the position of said seat element relative to said support element, including a bracket mounted on one of said elements for pivoting through a plurality of positions between an extended and a retracted position, and having a bight and two arms of predetermined lengths extending transversely of said bight toward said one element, an elongated lever having one end pivoted to one of said arms of said bracket and another end mounted at the seat for displacement relative thereto, a strap connected to the other of said elements and having a length substantially corresponding to said length of the other of said arms of said bracket, said other arm of said bracket being pivoted to said strap so that when said bracket is in said retracted position thereof, said other arm of said bracket is substantially coextensive with said strap and said bight of said bracket is proximate to said other element, and means for arresting said bracket in a selected one of said positions thereof.

Claim 12

In a seat, particularly a vehicle seat, a combination comprising a support element; a seat element above said support element; and means for adjusting the position of said seat element relative to said support element, including a bracket mounted on one of said elements for pivoting through a plurality of positions between an extended and a retracted position, and having a bight and two arms of predetermined lengths extending transversely of said bight toward said one element, an elongated lever having one end pivoted to one of said arms of said bracket and another end mounted at the seat for displacement relative thereto, a strap connected to the other of said elements and having a length substantially corresponding to said length of the other of said arms of said bracket, said other arm of said bracket being pivoted to said strap so that when said bracket is in said retracted position thereof, said other arm of said bracket is substantially coextensive with said strap and said bight of said bracket is proximate to said other element, and means for arresting said bracket in a selected one of said positions thereof.
