Patent CA-2111725-A1 (CA)
Title: Combination Reclining and Folding Mechanism for Automotive Seat Assemblies
Inventor: SMUK WOJCIECH
IPC: B60N2/30
Filed: 1993-12-18
Abstract: A latch mechanism is connected between the seatback member and the seat cushion member of a vehicle seat assembly to selectively control pivotal movement of the seatback member relative to the seat cushion member. A mounting mechanism is associated with each of the front and rear seat legs of the seat assembly and each such  mounting  mechanism  is  co-operable  with  a  respective attachment member affixed to the vehicle floor to permit movement of the seat cushion member from a first in-use position within the vehicle to a second forwardly translated stowed position within the vehicle.  The mounting member associated with at least one of the rear seat legs further comprises a lock mechanism that is selectively movable to restrainingly engage or disengage its respective attachment member.  A first actuation means is mounted on the seat assembly so as to be operatively moveable by a user from a neutral position,  whereat the latch means restrains pivotal movement of the seatback member, to an actuated position whereat pivotal movement of the seatback member is permitted.        A second actuation means is mounted on the seat cushion member and is operatively contacted by a portion of the seatback member upon forward pivoting of the seatback member, thereby causing unlocking the lock means, so as to permit movement of the seat cushion  member  from  its  in-use  position  to  its  forwardly translated stowed position upon continued pivotal movement of the seat cushion member.

IPC: A47C20/04
Filed: 1995-04-10
Abstract: The bed system has a rectangular frame, with a mattress assembly mounted on the frame. The mattress assembly has upper and lower wooden strip layers and intervening foam blocks. Each wooden strip layer has a plurality of relatively thin, somewhat flexible laterally-oriented wooden strips arranged in proximity to each other from top to bottom of the frame, with each strip extending from one side panel to the other side panel. There are three foam blocks, namelytwo outer foam blocks and one central foam block, running from head to foot of the bed between the wooden strip layers. A padded layer, preferably of foam approximately 5 cm thick, is positioned on top of the mattress assembly, extending substantially across the full width and length of the mattress assembly. Preferably positioned on top of the padded layer is a sheep's wool mattress pad, also with a cotton cover. Conventional sheets can be used to cover the mattress assembly, padded layer, and mattress pad. A sheep's wool duvet and sheep's wool pillow are preferably used to complete the bed system. The side panels have inwardly-facing shoulder portions running the length thereof, and the wooden strips of the lower wooden strip layer rest on the shoulder portions, with the outer foam blocks being in general vertical alignment with the outer walls of the side panels. Preferably the bed system includes at least one elevating mechanism to permit the head of the bed and/or lumbar and leg portions to be raised. In double, queen orking sized versions of the invention, a central support member runs longitudinally between the head and foot panels, with support rails on either side thereof. Twoof the mattress assemblies are arranged side by side, one on either side of the central support member.

Title: Toothbrush disinfection instrument
Inventor: CHAN EDDIE CHIN SUN
IPC: A61L2/18
Filed: 1995-05-31
Abstract: Among all the activities that are a part of our daily hygiene, there isone that is particularly contradictory in nature. The toothbrush that is used to maintain a clean and healthy mouth is also an instrument that can be heavily contaminated with microorganisms and can be the source of a variety of health problems. This invention is an instrument that is used along with an anti-infective agent to disinfect toothbrushes. The instrument consists of a reservoir containing one or more baffle(s) attached to its inside. The reservoir is filled with a disinfecting agent to kill microorganisms residing in the brush. The brush end of a toothbrush is inserted into the reservoir and moved in such a way that a fanning of the bristles is achieved when they are brought in contact with the baffle(s). This fanning action will assist in removing trapped food particles and facilitate the penetration of the disinfecting agent between the bristles. The brush is then removed from the reservoir to dry and the disinfecting agent is discarded.
