Abstract
A passenger seat frame assembly, including a seat bottom chassis including a plurality of leg modules and section assembly modules. The leg modules are attached to fixed, spaced-apart attachment points on a supporting surface, such as the deck of an aircraft fuselage. A plurality of beam elements are carried by the leg modules and section assembly modules. A plurality of clamp joints are provided for being positioned on the plurality of leg modules and for receiving the plurality of beam elements in spaced-apart relation to each other for defining a ladder frame assembly having a specified width and seat spacing.
Claims11
A passenger seat frame assembly, comprising:
- (a) a seat bottom chassis including a plurality of leg modules and section assembly modules, said leg modules for being attached to fixed, spaced-apart attachment points on a supporting surface;
- (b) a plurality of beam elements for being carried by said leg modules and section assembly modules;
- and
- (c) a plurality of clamp joints for being attached to the plurality of leg modules in a laterally offset position, each of said clamp joints including an elongate attachment element which enables attachment of said clamp joint to a left or right side of an upper portion of said leg modules, said clamp joints and said section assembly modules for receiving respective ones of the plurality of beam elements in spaced-apart relation to each other for defining a ladder frame assembly having a predetermined specified width and seat spacing.
A passenger seat, comprising:
- (a) a seat frame assembly, comprising:
- (i) a seat bottom chassis including a plurality of leg modules and section assembly modules, said leg modules for being attached to fixed, spaced-apart attachment points on a supporting surface;
- (ii) a plurality of beam elements for being carried by said leg modules;
- (iii) a plurality of clamp joints attached in a laterally offset position to a right or left side of said plurality of leg modules for receiving and clamping thereto respective ones of the plurality of beam elements to define a ladder frame assembly of spaced-apart leg modules and section assembly modules;
- (b) a seat bottom pan and a seat back pan carried by said frame assembly;
- and
- (c) a seat bottom cushion carried by said seat bottom pan and a seat back cushion carried by said seat back pan.
A method of mounting a passenger seat to attachment points on a supporting surface, comprising the steps of:
- (a) providing:
- (i) a seat bottom chassis including a plurality of leg modules and section assembly modules, said leg modules for being attached to fixed, spaced-apart attachment points on a supporting surface;
- (ii) a plurality of beam elements for being carried by said leg modules and section assembly modules;
- (iii) a plurality of clamp joints for being attached to a left or right side of an upper portion of the leg modules for receiving respective ones of the plurality of beam elements in spaced-apart relation to each other in a plurality of predetermined specified width and seat spacing configurations;
- (b) attaching first and second ones of the plurality of clamp joints to each of the leg modules in a laterally offset position;
- (c) positioning first and second beam elements laterally through the respective first and second clamp joints to attach the leg modules together in spaced-apart relation to each other;
- and
- (d) positioning a section assembly module on the beam elements adjacent each leg module.
