Abstract
A seat providing improved comfort includes a pair of moving seating assemblies. A motion mechanism provides each seating assembly with rocking movement and vertical movement. The seating assemblies are provided at a neutral angle that corresponds to the particular application of the seat. The amount of rocking movement and vertical movement is based on the neutral angle. In concert, the neutral angle orientation, rocking movement, and vertical movement cause the weight supported by an occupant's seat bones, posterior, and thighs to be optimally distributed on the seating assembly, improving seating comfort as applied to a given seating environment.
Claims52
A seat comprising:
- a pair of seating bodies, at least one motion mechanism providing the seating bodies with a total rocking motion and a vertical motion, each seating body having a predetermined neutral angle based on the particular application of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
A seat for optimally distributing the weight of an occupant's body borne by the ischial tuberosities and posterior over the seat regardless of an occupant's seating position, the seat comprising:
- a pair of seating assemblies, each seating assembly including a seat base, a cushion material supported by the base, and a cover for protecting the seating assembly;
- at least one support that supports said seating assemblies;
- at least one motion mechanism disposed between said at least one support and said seating assemblies, said at least one motion mechanism providing said seating assemblies with rocking movement and vertical movement;
- each seating assembly having (I) a predetermined neutral angle based on the particular application of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to earth's gravity vectors that the seating assembly naturally resides at when no external forces are present on the seating assembly;
- and (ii) a predetermined amount of total rocking motion and vertical motion provided in each seating assembly based on the neutral angle.
A seat comprising:
- a pair of seating assemblies, each seating assembly including a seat base, a cushion material supported by said seat base, and a cover which protects said cushion material and seat base;
- at least one support that supports said seating assemblies;
- at least one motion mechanism disposed between the seating assembly and the at least one support, said at least one motion mechanism providing rocking motion and vertical motion in said seating assemblies and an enlarged ideal sitting area for an occupant's ischial tuberosities;
- each seating assembly having a predetermined neutral angle based on the application of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to earth's gravity vectors that the seating assembly resides at when no external forces are present on the seating assembly, a predetermined amount of total rocking motion and vertical motion provided in each seating assembly based on the neutral angle.
A seat comprising:
- a pair of seating assemblies, at least one motion mechanism providing the seating assemblies with a rocking motion and a vertical motion, each seating assembly having a neutral angle, which is a non-zero angle that the seating assembly resides at with respect to a predefined axis when no external forces are present on the seat, the neutral angle ranging between approximately negative 40 degrees and positive 30 degrees, a predetermined amount of vertical motion and total rocking motion provided in each seating assembly based on the neutral angle of the seating assemblies, the amount of vertical motion ranging between approximately 0.1 and 4 inches, and the amount of total rocking motion being up to approximately 60 degrees.
A seat comprising:
- a pair of seating bodies, each having a ischial tuberosities target area extending about 5 inches in the longitudinal direction of the seating body forward of and about 5 inches rearward of said motion mechanism and up to the width of the seating body;
- a pair of motion mechanisms, each respectively associated with one seating body, each motion mechanism providing its respective seating body with a rocking motion and a vertical motion, and each motion mechanism having at least two points of physical contact with its associated seat body.
