What is claimed is:
1. A seat device of a vehicle comprising;
a substantially flat floor surface substantially extending across a full cabin space of the vehicle,
front row seats, center row seats and a rear row seat disposed in a longitudinal direction of the vehicle on the floor surface,
a seat storage pan extending rearward the rear row seat and downward a level of the floor surface,
the front row seats being disposed with a space,
the center row seats including a plurality of seats in which at least one of the seats is movable in a lateral direction of the vehicle,
when the rear row seat is received in the seat storage pan, a substantially flat and continuous surface of a substantially same level as the floor surface being formed rearward the center row seats to a rear end of the cabin space with a substantially full width of the cabin space,
when the center row seats are disposed offset to one side of the vehicle with regard to the lateral direction, a substantially flat and continuous surface of a substantially same level as the floor surface being formed rearward the front row seats to a rear end of the cabin space, and
when the center row seats are disposed to produce a space at a central portion of the vehicle in the lateral direction, a substantially flat and continuous surface of a substantially same level as the floor surface being formed rearward the front row seats to a rear end of the cabin space at a central portion of the cabin space in the lateral direction.
2. A seat device as recited in claim 1 wherein the front row seats include a driver’s seat and an assistant’s seat, the assistant’s seat being movable in the longitudinal direction, and at least one of the center row seats which is disposed at a side of the assistant’s seat in the lateral direction being movable in the lateral direction.
3. A seat device as recited in claim 1 wherein the center row seats are movable in both the longitudinal and lateral directions, and a longitudinal sliding mechanism for allowing a longitudinal movement of the center row seats being disposed over a lateral sliding mechanism for allowing a lateral movement of the center row seats.
4. A seat device as recited in claim 1 wherein a slide rail for allowing a sliding movement of the central row seats is provided with a mechanism through which a seat is removed from the slide rail.
5. A seat device as recited in claim 1 wherein a door opening is formed at a longitudinal side of a vehicle corresponding the center row seats, and a side door for a sliding movement being combined with the door opening.
6. A seat device of a vehicle comprising
a substantially flat floor surface substantially extending across a full cabin space of the vehicle,
a front row seat, center row seat and rear row seat disposed in a longitudinal direction of the vehicle on the floor surface,
each of the seats being movable in both the longitudinal and lateral directions of the vehicle through a longitudinal sliding mechanism for allowing the seat of a longitudinal movement and a lateral sliding mechanism for allowing the seat of a lateral movement,
either one of the longitudinal and lateral sliding mechanisms being mounted on a body side of the vehicle,
the other of the sliding mechanism being mounted on the seat so as to be moved together with the seat, and
the sliding mechanism mounted on the body side of the vehicle being provided with a removable mechanism through which the seat is removed.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An apparatus for detecting a key insertion into a lock or a key removal from the lock, comprising:
a movement sensing device attached to the key and configured to sense a translational movement of the key along the longitudinal axis of the key during the key movement in the lock by varying signals generated in time domain responsive to variations in the shape of the key as the key moves with translational motion in the lock; and
a processing unit configured to process the varying signals, sensed by and received from said movement sensing device, by at least converting the variations of the signals to discrete digital pulses,
wherein a key insertion or a key removal is determined based on at least one of configurable predefined parameters and programmable predefined parameters, the configurable and programmable parameters each comprising:
the number of pulses, the number of digital pulses within a predefined period, a predefined maximal spacing between consecutive pulses, or any combination thereof,
and wherein a differentiation between a key insertion and a key removal is determined by at least one of: detecting the phase difference between the corresponding sensed signals, memorizing the last insertion event such that subsequent signals are identified as a removal event, and a combination thereof.
2. An apparatus according to claim 1, wherein the movement sensing device is at least one accelerometer.
3. An apparatus according to claim 1, wherein the processing unit includes an electronic circuit for converting signals from the movement sensing device into digital pulses.
4. An apparatus according to claim 1, wherein the digital pulses are generated when the signals from the movement sensing device exceed a predefined threshold level.
5. An apparatus according to claim 2 wherein the accelerometer is a digital accelerometer which provides digital signals.
6. An apparatus according to claim 1, wherein the predefined parameters are configured by a calibration process.
7. An apparatus according to claim 6, wherein the predefined parameters are configured by a calibration process initiated by a key insertion or a key removal.
8. A method for detecting a key insertion into a lock or a key removal from the lock, comprising:
moving the key in the lock along the longitudinal axis of the key, thereby generating signals in time domain responsive to variations in the shape of the key, during the key movement along the longitudinal axis, by a movement sensing device attached to the key;
converting the variations of the signals to discrete digital pulses;
determining a key insertion or a key removal based on at least one of a configurable and programmable parameter, the configurable and programmable parameters each comprising:
the number of pulses, the number of digital pulses within a predefined period, a predefined maximal spacing between consecutive pulses, or any combination thereof;
and wherein a differentiation between a key insertion and a key removal is determined by at least one of: detecting the phase difference between the corresponding sensed signals, memorizing the last insertion event such that subsequent signals are identified as a removal event, and a combination thereof.
