Invacare Corporation One Invacare Way PO Box 4028 Elyria, Ohio 44036 Phone: (440) 329-6000 Facsimile: (440) 365-4558 Contact Person: Rae Ann Farrow Manager, Regulatory Compliance Date Prepared: October 19, 2001 #### Name of Device and Name/Address of Sponsor Invacare Elevating Seat Option Invacare Corporation One Invacare Way Elyria, Ohio 44036-2028 Phone: (440) 329-6000 Facsimile: (440) 365-4558 # Common or Usual Name Elevating Seat #### Classification Name Wheelchair, Powered #### Predicate Devices Accelerated Rehab Designs, Inc. "E-2000 Power Elevating Seat System" (K992828, 2/3/2000) #### Intended Use The intended function and use of the Invacare Elevating Seat is to provide powered elevation of the wheelchair seat and user in order to assist the user with daily activities, transfers and general accessibility. {1}------------------------------------------------ # Technological Characteristics and Substantial Equivalence ## A. Device Description The Invacare Elevating Seat consists of a pedestal actuator, mounting weldments with mounting hardware, and a toggle control. The intended function and use of the elevating seat is to provide powered elevation of the wheelchair seat and user in order to assist the user with daily activities, transfers and general accessibility. The bottom of the actuator assembly is mounted to the base of the wheelchair via the seat support weldment, which is specific to the particular wheelchair model. The top of the actuator assembly mounts to the wheelchair seat assembly via the seat mount bracket, which is specific to the seat assembly of the wheelchair. The ball drive pedestal actuator has a load capacity of 500 pounds and a maximum stroke of 8 inches. The elevating seat is available for select models of power wheelchair as a factory installed option. The MIV Elevating Seat Toggle is standard with the elevating seat option. It is a DC brush type motor controller that is used to control the elevating actuator on power wheelchair systems with the elevating seat option installed. A double throw momentary position switch is used to drive the actuator. Current through the motor is limited and drive speed reduction occurs when the chair is in an elevated position. The MIV Elevating Seat Toggle connects to the Power Take Off (PTO) connector of the wheelchair battery harness. Therefore, the power supply for the elevating seat toggle is taken directly from the wheelchair battery harness through a 15 amp fused power block, and the elevate function can be activated even when the wheelchair drive controls are turned off. The MIV Elevating Seat Toggle also connects to a proximity switch, which senses when the seat is elevated. When the switch senses that the seat is elevated more than .75 inches, the speed of the wheelchair is reduced to 20% of the maximum possible speed of the chair. However, the reduced speed will not exceed the user-programmed speed. # MKIV TAC For certain wheelchair models, the MIV TAC, a two-actuator control, is available as an option to the MIV Elevating Seat Toggle. The MIV TAC allows the elevating seat to be combined with the tilt feature of the wheelchair seating system and it allows the elevating seat to be controlled through the joystick of the wheelchair. In addition to the features described under the MIV Elevating Seat Toggle, the MIV TAC has an additional tilt sensor that detects the overall back angle of the seating system. If the seat is tilted more than 20 degrees the elevating seat will not elevate. Also, if the seat is elevated more than .75 inches, the seat will not tilt. {2}------------------------------------------------ The MIV Elevating Seat Toggle and the MIV TAC are to be used in conjunction with the Invacare Model MCC-MKIV Motor Controller , Joystick and options. FDA granted this controller marketing clearance on June 2, 1994, under 510(k) Accession Number K940972. # B. Substantial Equivalence The Invacare Elevating Seat is substantially equivalent to the Accelerated Rehab Designs, Inc. "E-2000 Power Elevating Seat System" (K992828, 2/3/2000). # PERFORMANCE DATA The Invacare Elevating Seat meets the applicable requirements specified in the Rehabilitation Engineering Society of North America (RESNA) Standard ANSI/RESNA WC/14 (1991) and ISO Standard ISO 7176: 1993(E), "ISO Standard, Wheelchairs -Requirements and Test Methods for the Power and Control Systems of Electric Wheelchairs." {3}------------------------------------------------ Image /page/3/Picture/2 description: The image shows the logo for the U.S. Department of Health & Human Services.
