Total Claims: 16
Claim 1
Independent Claim
239 words
A seat, comprising: a first structure constituting a structural base of a seat cushion part of the seat; a second structure constituting a structural base of a seat back part of the seat; a third structure constituting a structural base of an arm rest device, comprising a holding structure secured to said first structure and latching means for detachably latching said third structure to said holding structure when said third structure is properly held by said holding structure, wherein said holding structure comprises a metallic stay member of generally L-shaped cross section, said stay member being secured at a first wing part thereof to a bottom part of said first structure and having a second wing part raised upward and a resilient metal plate secured at its lower end to said first wing part of said stay member in such a manner as to leave a restricted predetermined clearance between the metal plate and the second wing part of said stay member said predetermined clearance being sized so as to neatly receive a part of said third structure; first means for detachably connecting said third structure to said first structure; a single cover member covering said first, second and third structures; second means for detachably fastening a peripheral edge of said cover member to a selected portion of said third structure; and an arm rest pad which is put on said third structure and covered with said cover member.
Claim 2
Dependent Claim
239 words
A seat, comprising: a first structure constituting a structural base of a seat cushion part of the seat; a second structure constituting a structural base of a seat back part of the seat; a third structure constituting a structural base of an arm rest device, comprising a holding structure secured to said first structure and latching means for detachably latching said third structure to said holding structure when said third structure is properly held by said holding structure, wherein said holding structure comprises a metallic stay member of generally L-shaped cross section, said stay member being secured at a first wing part thereof to a bottom part of said first structure and having a second wing part raised upward and a resilient metal plate secured at its lower end to said first wing part of said stay member in such a manner as to leave a restricted predetermined clearance between the metal plate and the second wing part of said stay member said predetermined clearance being sized so as to neatly receive a part of said third structure; first means for detachably connecting said third structure to said first structure; a single cover member covering said first, second and third structures; second means for detachably fastening a peripheral edge of said cover member to a selected portion of said third structure; and an arm rest pad which is put on said third structure and covered with said cover member.
Claim 3
Dependent Claim
61 words
