Description

COMFORT BUCKET SEAT

The present invention relates to a comfort bucket seat, and more specifically, to a vehicle comfort bucket seat in which a pneumatic device and a ventilation device are easily installed on a bucket seat to maintain a stable driver's posture during high-speed driving and turning, thereby improving comfort performance.

Typically, high-performance vehicles such as sports cars, including sports sedans and sports coupes, as well as vehicles for racing, are equipped with bucket seats to provide a stable driving position.

The above bucket seat is manufactured with a complex shape that can wrap around the driver's body to maintain a stable driving posture and prevent the vehicle from leaning to the left or right during high-speed driving or high-speed turning.

Moreover, unlike comfort seats used in general vehicles, the bucket seats are manufactured with a slim structure that provides a firm and narrow seating feel to maintain a stable driving position while providing a dynamic driving feel.

However, in the case of the bucket seat, since it is manufactured with a slim and lightweight structure that is narrower and thinner than the comfort seats of general vehicles, it has the advantage of being able to tightly wrap the driver's body to maintain a stable driving posture and prevent the driver from leaning left and right, but there is a problem in that the internal space of the seat is narrow, making it impossible to install a pneumatic device that provides cushion support and a ventilation device that provides cooling air.

Ultimately, there is a problem that the comfort performance of the bucket seat is bound to be reduced because the pneumatic device or ventilation device cannot be easily installed on the existing bucket seat.

The present invention has been made to solve the above-mentioned problems of the related art, and the purpose of the present invention is to provide a vehicle comfort bucket seat that can maintain a slim and lightweight structure while improving comfort performance and convenience by easily installing a pneumatic device and a ventilation device on the bucket seat to maintain a stable driver's posture during high-speed driving and turning.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

The attached drawings 1 and 2 illustrate a pneumatic device installed in a comfort bucket seat according to the present invention, and Drawing 5 illustrates a ventilation device installed in a comfort bucket seat according to the present invention.

As shown in FIGS. 1, 2 and 5, the bucket seat (10) is manufactured with a slim structure that provides a firm and narrow seating feel to maintain a stable driving posture while feeling a dynamic driving feel, unlike a comfort seat applied to a general vehicle.

To this end, the bucket seat is configured to include a slim seat back pad (30) having a headrest pad (20) integrally formed on the upper portion, a seat back board (40) having a headrest board (42) integrally formed on the upper portion, and attached to the back surface of the seat back pad (30), and a slim seat cushion pad (70) mounted on a seat cushion frame (60).

In addition, a bolster part (22) that wraps around and supports the upper body side of the driver or passenger is integrally formed on both sides of the seatback pad (30).

Of course, the seat back pad (30) and the seat back board (40) are covered with a seat back cover (50), and the seat cushion pad (70) is covered with a seat cushion cover (80).

Preferably, the seat back board (40) may be provided as a plastic injection molded product having a predetermined thin thickness as a skeleton supporting the seat back pad (30).

The present invention focuses on the point that by easily installing a pneumatic device and a ventilation device in a bucket seat having the above-mentioned structure, the comfort performance by the pneumatic device and the convenience by the ventilation device can be improved while maintaining a slim and lightweight structure.

The above pneumatic device can provide comfort support to the driver and passengers by expanding and contracting the headrest, expanding and contracting the bolster, expanding and contracting the lumbar support of the seatback pad, and expanding and contracting for tilting the front end of the seat cushion, and can be installed between the headrest pad (20) and the headrest board (42), between the seatback pad (30) and the seatback board (40), and between the seat cushion pad (70) and the seat cushion frame (60).

As shown in FIGS. 1 and 2, the pneumatic device comprises: a first air cell (110) that is expandable and contractible and is positioned between the headrest pad (20) and the headrest board (42); a first support plate (150) that is attached to the front side of the headrest board (42) and supports the expansion and contraction operation of the first air cell (110); a second air cell (120) that is expandable and contractible and is positioned between the seatback pad (30) and the seatback board (40); a second support plate (160) that is attached to the front side of the seatback board (40) and supports the expansion and contraction operation of the second air cell (120); a pair of third air cells (130) that are expandable and contractible and are positioned on the front side lower surface of the seat cushion pad (70); and a second air cell (130) that is attached to the seat cushion frame (60) and supports the expansion and contraction operation of the third air cell (130). It is composed of a third support plate (170).

In addition, the fourth air cell (140) is further positioned in the inner part of the bolster part (22) formed on both sides of the seat back pad (30) so as to be expandable and contractible.

At this time, an air pump (180) driven to supply and discharge air through an air hose (182) having a predetermined length is connected to the first air cell (110), the second air cell (120), the third air cell (130), and the fourth air cell (140).

Meanwhile, the first support plate (150) is supported in close contact with the back surface of the first air cell (110) to guide the expansion of the first air cell (110) so that it can be directed forward (to the head of the driver or passenger), the second support plate (160) is supported in close contact with the back surface of the second air cell (120) to guide the expansion of the second air cell (120) so that it can be directed forward (to the waist of the driver or passenger), and the third support plate (170) is supported in close contact with the bottom surface of the third air cell (130) to guide the expansion of the third air cell (130) so that it can be directed upward (to the knees and thighs of the driver or passenger).

Preferably, the first support plate (150), the second support plate (160), and the third support plate (170) can be manufactured in a plate shape of a predetermined area using expanded polypropylene (EPP: Expanded Polypropylene) material to reduce weight.

The attached drawing 3 is a cross-sectional view showing an example of operation of a pneumatic device installed in a comfort bucket seat according to the present invention, and reference numeral 24 designates a sponge pad attached to the front of a headrest pad (20) to provide a cushioning feeling to the head of a driver or passenger.

When air is supplied to the first air cell (110) through the air hose (182) by driving the air pump (180), as shown in FIG. 3, the first air cell (110) expands toward the front (head of the driver or passenger) and at the same time, the first support plate (150) is supported in close contact with the rear surface of the first air cell (110), thereby guiding the expansion of the first air cell (110) to be toward the front (head of the driver or passenger).

Accordingly, the forward/backward position and support force of the headrest for the driver's or passenger's head can be adjusted to a desired level by the expansion of the first air cell (110).

In addition, when air is supplied to the second air cell (120) through the air hose (182) by driving the air pump (180), the second air cell (120) expands toward the front (the waist of the driver or passenger) and at the same time, the second support plate (160) is closely supported by the rear surface of the second air cell (120) to guide the expansion of the second air cell (120) toward the front (the waist of the driver or passenger), so that, as illustrated in FIG. 4, the front-rear position and support force of the seatback for the waist of the driver or passenger can be adjusted to a desired level by the expansion of the second air cell (120).

In addition, when air is supplied to the third air cell (130) through the air hose (182) by driving the air pump (180), the third air cell (130) expands upward (to the driver's or passenger's knees and thighs) and at the same time, the third support plate (170) is closely supported by the lower surface of the third air cell (130) to guide the expansion of the third air cell (130) upward (to the driver's or passenger's knees and thighs), so that, as illustrated in FIG. 4, the tilting angle and support force of the front end of the seat cushion that supports the driver's or passenger's knees and thighs can be adjusted to a desired level by the expansion of the third air cell (130).

In addition, when air is supplied to the fourth air cell (140) through the air hose (182) by driving the air pump (180), as shown in FIG. 4, the supporting force of the bolster part (22) supporting the upper body side of the driver or passenger can be adjusted to a desired level by the expansion of the fourth air cell (140).

In this way, by installing a pneumatic device including an air cell in the headrest, seatback, and seat cushion of the bucket seat so that the pneumatic device can be inflated or deflated to suit the seat position desired by the driver and passenger, the comfort performance of the bucket seat can be improved.

The above ventilation device is intended to prevent sweating due to the bucket seat tightly wrapping the driver and passengers while providing a comfortable seat feeling by discharging air toward the bodies of the driver and passengers through the seat back and seat cushion, and can be installed across the seat back pad (30) and seat back board (40), as well as the seat cushion pad (70) and the lower space of the seat cushion pad (70).

As shown in FIGS. 5 to 8, the ventilation device comprises a first air distribution passage (31) formed in the front of the seatback pad (30) to discharge air toward the upper bodies of the driver and passenger through the seatback, an air passage hole (32) formed forward and backward through the lower portion of the seatback pad (30) to communicate with the first air distribution passage (31), and a back duct (44) formed in the lower portion of the seatback board (40) and connected to the air passage hole (32).

Preferably, the first air distribution path (31) of the seat back pad (30) is formed in a “U”-shaped concave groove shape to evenly distribute air over the entire surface of the seat back.

In particular, a back tape (34) having a plurality of first air discharge holes (33) is attached to the front side of the seat back pad (30) to cover the first air distribution path (31).

At this time, the back tape (34) has the function of preventing the first air distribution path (31) of the seatback pad (30) from being deformed as the driver's or passenger's expected body load is applied to the seatback pad (30), and also has the function of discharging the air flowing through the first air distribution path (31) to the front of the seatback through the first air discharge hole (33).

Preferably, a sealing (36) made of synthetic rubber (EPDM: Ethylene Propylene Diene Monomer) is installed at the connection between the air passage hole (32) of the seat back pad (30) and the back duct (44) to prevent air leakage, i.e. to maintain airtightness.

In addition, the ventilation device is configured to include an air leak blocking plate (78) attached to the lower surface of the seat cushion pad (70) and configured to have a structure in which a plurality of second air discharge holes (72) are formed vertically penetrating the seat cushion pad (70) to discharge air toward the lower bodies of the driver and passengers through the seat cushion, a second air distribution channel (74) formed on the lower surface of the seat cushion pad (70) to communicate with the plurality of second air discharge holes (72), and an air supply hole (76) communicated with the second air distribution channel (74).

At this time, the air leak blocking plate (78) serves to prevent air supplied to the second air distribution path (74) of the seat cushion pad (70) from leaking to the outside.

Preferably, the second air distribution path (74) of the seat cushion pad (70) is formed in an “H”-shaped concave groove shape to evenly distribute air over the entire surface of the seat cushion.

In addition, the ventilation device includes an air blower (90) that is connected to the back duct (44) and the air supply hole (76) of the air leak blocking plate (78) so as to be able to supply air.

Preferably, the air blower (90) is provided with a structure having a two-way discharge pipe, such that the first discharge pipe (91) of the two-way discharge pipes is connected to the air supply hole (76) of the air leak blocking plate (78) so as to be able to supply air, and the second discharge pipe (92) is connected to the back duct (44) so as to be able to supply air.

Meanwhile, since the air blower (90) is mounted on the seat cushion frame, the back duct (44) formed on the air blower (90) and the seat back board (40) is spaced apart at a certain angle and distance, so the second discharge pipe (92) of the air blower (90) and the back duct (44) formed on the seat back board (40) are connected by a connecting duct (94) of a bellows type that can be bent at a certain angle.

Accordingly, when the air is discharged through the second discharge pipe (92) and the connecting duct (94) due to the operation of the air blower (90), the air sequentially passes through the back duct (44) formed in the seat back board (40) and the air passage hole (32) formed in the lower part of the seat back pad (30), flows into the first air distribution path (31) formed in the front part of the seat back pad (30), and can then be discharged to the front of the seat back through the first air discharge hole (33) of the back tape (34) from the first air distribution path (31).

Accordingly, the air discharged to the front of the seat back through the first air discharge hole (33) of the back tape (34) is finally discharged toward the upper body of the driver or passenger through micro holes (not shown) formed in the seat back cover, thereby preventing sweating due to the seat back of the bucket seat tightly wrapping the driver and passenger, and providing a comfortable seat feeling.

Alternatively, when the air is discharged through the first discharge pipe (91) to the air supply hole (76) of the air leak blocking plate (78) due to the operation of the air blower (90), the air may flow to the second air distribution path (74) of the seat cushion pad (70) and then be discharged upward of the seat cushion through the second air discharge hole (72).

Accordingly, the air discharged upward through the second air discharge hole (72) of the seat cushion pad (70) is finally discharged toward the lower body of the driver or passenger through micro holes (not shown) formed in the seat cushion cover, thereby preventing sweating due to the seat cushion of the bucket seat tightly wrapping the driver and passenger, and providing a comfortable seat feeling.

In this way, the slim and lightweight structure of the bucket seat can be maintained to maintain a stable driver posture during high-speed driving and turning, while improving comfort performance through a pneumatic device and convenience through a ventilation device.
