US 6,672,661 B2 · Passenger seat, passenger seat leg module and method

Abstract

A passenger seat which includes a seat bottom chassis assembled from a plurality of leg modules attached to fixed, spaced-apart attachment points on a supporting surface, and a plurality of beam elements for being carried by the leg modules. A plurality of clamp joints are positioned on a first side of the leg modules in a first laterally-offset relation thereto in a first spaced-apart relation to the attachment points of the supporting surface and for receiving the plurality of beam elements for defining a ladder frame assembly having a first specified width and seat spacing. The plurality of clamp joints are removable from the first side of the leg modules can positioned on a second, opposite side of the leg modules in a second laterally-offset relation for defining a ladder frame assembly having a second specified width and seat spacing while the plurality of leg modules maintain the same position relative to each other and thus to the fixed, spaced apart attachment points whereby the location of the seats may be altered while using the same beam elements.

Dependent claims

A passenger seat, comprising:

(a) a seat bottom chassis including a plurality of leg 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;
(c) a plurality of clamp joints for being positioned on a first side of said leg modules in a first laterally-offset relation thereto in a first spaced-apart relation to the attachment points of the supporting surface and for receiving the plurality of beam elements for defining a ladder frame assembly having a first specified width and seat spacing;
and
(d) said plurality of clamp joints being removable from the first side of said leg modules and positioned on a second, opposite side of said leg modules in a second laterally-offset relation thereto for defining a ladder frame assembly having a second specified width and seat spacing while the plurality of leg modules maintain the same position relative to each other and thus to the fixed, spaced apart attachment points whereby the location of the seats may be altered while using the same beam elements.

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, said leg modules for being attached to fixed, laterally spaced-apart attachment points on a supporting surface;
(ii) a plurality of laterally-extending beam elements for being carried by said leg modules;
(iii) a plurality of clamp joints;
(b) attaching a clamp joint to a selected left or right lateral side of each of said leg modules for clamping the plurality of leg modules together in spaced-apart relation to each other, each said clamp joint having an attachment element connected to said leg module and an annular collar element which protrudes above the top o said leg module for receiving a laterally-extending beam therethrough;
and
(c) extending the plurality of beam elements through said annular collar elements in said clamp joints for defining a ladder frame assembly having a predetermined width and seat spacing, wherein each of said beams continuously spans at least two of said leg modules.
