Abstract

Claims (41)

1. An armrest assembly for a seat comprising:

an armrest; and an armrest coupling assembly for coupling said armrest to said seat comprising:

a linear adjustment mechanism coupled to said armrest, said linear adjustment mechanism defining an initial linear axis and arranged to enable said armrest to selectively translate along said initial linear axis between a plurality of generally vertical positions;

said linear adjustment mechanism further comprising:

a housing attached to said seat, said housing helping define said linear axis and including a plurality of housing slots spaced within said housing;

a sliding mechanism positioned within said housing and connected to said armrest, said sliding mechanism further arranged to translate within said housing and engage one of said plurality of housing slots;

a release mechanism connected to said sliding mechanism, said release mechanism arranged to enable said sliding mechanism to disengage from one of said plurality of housing slots;

a rotational adjustment mechanism coupled to said armrest, said rotational adjustment mechanism defining a rotational axis and arranged to enable said armrest to selectively pivot about said rotational axis between a plurality of angular positions;

said rotational adjustment mechanism further comprising:

a first pivot formed between said armrest and said linear adjustment mechanism;

a second pivot formed between said linear adjustment mechanism and said seat, said second pivot arranged to enable said rotational adjustment mechanism to adjust angular orientation of said linear adjustment mechanism to define a plurality of subsequent linear axes;

each of said plurality of subsequent linear axes having a greater horizontal component than said initial linear axis

a disc attached to said seat, said disc helping to define said rotational axis and including a plurality of disc slots spaced within said disc;

a pin connected to said linear adjustment mechanism, said pin arranged to pivot about said disc and engage one of said plurality of disc slots; and

a pin release mechanism connected to said pin, said pin release mechanism arranged to enable said pin to disengage from one of said plurality of disc slots.

2. The armrest assembly of claim 1 wherein said plurality of disc slots further comprises a plurality of holes disposed along a perimeter of said disc.

3. The armrest assembly of claim 1 wherein said plurality of disc slots further comprises a plurality of indentations disposed along a perimeter of said disc.

4. The seat assembly of claim 1 wherein said disc further includes a channel disposed along a perimeter of said disc arranged to receive said pin.

5. The seat assembly of claim 1 wherein said pin release mechanism comprises a push button.

6. The seat assembly of claim 1 wherein said pin release mechanism comprises a pull tab.

7. A seat assembly for a vehicle comprising:

a seat

an armrest; and an armrest coupling assembly for coupling said armrest to said seat comprising:

a linear adjustment mechanism coupled to said armrest, said linear adjustment mechanism defining an initial linear axis and arranged to enable said armrest to selectively translate along said initial linear axis between a plurality of generally vertical positions;

said linear adjustment mechanism further comprising:

a housing attached to said seat, said housing helping to define said linear axis and including a plurality of housing slots spaced within said housing;

a sliding mechanism positioned within said housing and connected to said armrest said sliding mechanism further arranged to translate within said housing and engage one of said plurality of housing slots;

a release mechanism connected to said sliding mechanism, said release mechanism arranged to enable said sliding mechanism to disengage from one of said plurality of housing slots;

said armrest further arranged to pivot relative to said sliding mechanism, said housing, and said seat;

said housing further comprising a bracket assembly, said bracket assembly further comprising:

an anchoring portion having a generally straight cross section for anchoring said bracket assembly to said seat;

at least one housing portion connected to said anchoring portion and having one of a generally “U” or “C”-shaped cross section wherein said sliding mechanism is contained within said housing portion;

a rotational adjustment mechanism coupled to said armrest, said rotational adjustment mechanism defining a rotational axis and arranged to enable said armrest to selectively pivot about said rotational axis between a plurality of angular positions;

said rotational adjustment mechanism further comprising:

a first pivot formed between said armrest and said linear adjustment mechanism;

a second pivot formed between said linear adjustment mechanism and said seat, said second pivot arranged to enable said rotational adjustment mechanism to adjust annular orientation of said linear adjustment mechanism to define, a plurality of subsequent linear axes.

8. The seat assembly of claim 7 wherein said plurality of linear position spaces further comprises a plurality of holes disposed along said anchoring portion of said housing.

9. The seat assembly of claim 7 wherein said rotational adjustment mechanism further comprises:

a disc attached to said seal, said disc helping to define said rotational axis and including a plurality of disc slots spaced within said disc;

a pin connected to said linear adjustment mechanism, said pin arranged to pivot about said disc and engage one of said plurality of disc slots; and

a pin release mechanism connected to said pin, said pin release mechanism arranged to enable said pinto disengage from one of said plurality of disc slots.
