Lightweight seat
Disclosed is a lightweight seat ( 100 ) that includes a seat base ( 102 ), a seat bottom ( 103 ) attached to an upper portion of the seat base, a seat back ( 101 ) attached to a rear portion of the seat bottom, and a seat belt assembly ( 150 ) secured to the seat bottom. The seat belt assembly may include a strap ( 104 ) attached to an underside of the seat bottom and extending from a first end adjacent to first side of the seat bottom to a second end adjacent to a second side of the seat bottom and a seat belt disposed adjacent to an upper side of the seat bottom, wherein a first end of the seat belt is attached to the first end of the strap and a second end of the seat belt is attached to the second end of the strap.
1. A seat comprising:
a seat base;
a seat bottom attached to an upper portion of the seat base;
a seat back attached to a rear portion of the seat bottom; and
an arm rest assembly attached to the seat bottom configured to move between a deployed position and a stowed position, wherein the arm rest assembly comprises:
an arm rest comprising:
a first portion having a first end and a second end;
a second portion attached to the second end of the first portion; and
a tapered stud fitting extending from the first portion in a direction approximately parallel to a longitudinal axis of the first portion; and
an articulating fitting attached to the seat bottom and comprising an elongated slot, a rotation slot, and a locking cavity;
wherein the arm rest is pivotable over a range of approximately 90 degrees with respect to the articulating fitting;
wherein the tapered stud fitting engages:
the locking cavity when the arm rest is in the deployed position; and
the rotation slot during movement between the deployed position and the stowed position;
wherein movement of the tapered stud fitting into the locking cavity simultaneously causes a pin of the arm rest to traverse along the elongated slot.
2. The seat of claim 1 , wherein the arm rest rotates about the pin.
3. The seat of claim 2 , wherein the rotation slot comprises an arc centered about the elongated slot in the articulating fitting.
4. The seat of claim 1 , wherein:
the tapered stud fitting has a partial cone shape and the locking cavity has a complementary shape.
5. The seat of claim 1 , wherein the pin is cylindrical.
6. An arm rest assembly comprising:
an arm rest comprising
a first portion having a first end and a second end; and
a second portion attached to the second end of the first portion; and
a stud fitting extending from the first portion; and
an articulating fitting comprising an elongated slot, a rotation slot, and a locking cavity;
wherein the stud fitting engages:
the locking cavity when the arm rest is in a deployed position; and
the rotation slot during movement between the deployed position and a stowed position;
wherein movement of the stud fitting into the locking cavity simultaneously causes a pin of the arm rest to traverse along the elongated slot.
7. The arm rest assembly of claim 6 , wherein the stud fitting comprises an axial direction that is approximately parallel to a longitudinal axis of the first portion.
8. The arm rest assembly of claim 6 , wherein the arm rest pivots over a range of approximately 90 degrees with respect to the articulating fitting during movement between the deployed position and the stowed position.
9. The arm rest assembly of claim 6 , wherein the arm rest rotates about the pin.
10. The arm rest assembly of claim 6 , wherein
the stud fitting has a partial cone shape and the locking cavity has a complementary shape.
