Title: Easy entry assist mechanism for vehicle pivotal seat
Inventor: SCHWARTZ MARTIN T
IPC: B60N2/10
Filed: 1987-11-19
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE         A gas spring assisted latch assembly for an automotive vehicle seat structure which tilts the seat forwardly to an easy entry position without passenger assistance upon release of the latch.  An extensible and retractable gas spring actuator is provided constantly biased toward its extended position.  The actuator, which has its one end pivotally connected to the seat riser and its other end pivotally connected to the vehicle floor, is held in its retracted position by a latch mechanism releasably locking the seat structure in its upright mode.  Release of the latch mechanism allows the actuator to apply a constant pushing force pivoting the seat to its forwardly tilted position.  An improved dual actuated latch mechanism provides  an alternative outboard side latch release handle for ready access from outside the vehicle in combination with an existing rear latch release handle.

Abstract: An expandable pouch is provided for applying a pressure to a material in a container so that it may be readily dispensed therefrom and comprises two flat sheets of a gas and liquid impermeable material in superposed relationship so as to have a length and a width and with the peripheral edge portions thereof permanently sealed.  A plurality of compartments are formed in the expandable pouch by lengthwise extending semipermanent peelable strips.  Two components of a chemical gas generating system having a delayed action system associated therewith are located in one of the compartments and one component of the two components is located in the other compartments.  After actuation of the two components, the one compartment will gradually expand and as the material is dispensed will rupture the semipermanent peelable strip between it and the next adjacent other compartment to form one combined compartment with the one component in the next adjacent other compartment continuing the gas generating system.  This process continues until all the other compartments have been expanded.  Also, an expandable pouch particularly designed for cooperation with a specifically shaped container is provided wherein the other compartments are expanded so as to maintain a substantially constant pressure in the container.

Abstract: ROGERS, BERESKIN & PARR            INVENTORS:  Bruce B. Gamble Douglas A. Snowdon TITLE:     "BREATHING SYSTEM"           ABSTRACT OF THE DISCLOSURE           A respiratory apparatus,  which receives exhaled gas from a user, removes carbon dioxide from and introduces oxygen into the exhaled gas, to present a breathing gas to a user.   A respiratory  flow transducer  in the  respiratory apparatus is subjected to the breathing gas demand of the user.  Oxygen is introduced into the breathing system by an oxygen flow regulator connected to an oxygen supply inlet.          The  respiratory  flow  transducer  and  the  oxygen  flow regulator  are  connected  by  a  linkage.     The  linkage constrains the oxygen flow regulator and respiratory flow transducer  to  operate  together  whereby   there   is   a substantially constant ratio between the breathing gas flow rate and the oxygen flow rate.     An air bleed system can be connected to an air inlet to introduce air into the respiratory apparatus and to displace  a  portion  of  the  gas  from  the  respiratory apparatus.  The  air  bleed  system  ensures  a  relatively constant oxygen concentration in the breathing gas presented to the user despite varying oxygen demands placed upon the respiratory apparatus by the user.
